Last week, Warren Gatland named 10 uncapped players in his World Cup training squad.
Over the coming weeks, that 54-man squad will gradually decrease - becoming 45 ahead of the summer training camps early in July, then 33 for the tournament in France.
But which of the 10 players yet to pull on the red jersey have a chance of making it to that final squad and just what could they offer?

Kemsley Mathias
Scarlets loose-head Kemsley Mathias has been a constant in the west Walians side since December. The fact they finished the season strongly probably isn't a coincidence.
The balance of power has shifted in Llanelli, with Mathias outperforming British and Irish Lion Wyn Jones over the course of the campaign to get in to the Wales squad ahead of his fellow front-rower.
There's a reason many fans down west were delighted he recently signed a new deal with the Scarlets. There's nothing overly flashy about the 23-year-old, but he's been one of the shining lights for Peel's side this year.
Part of the reason Gatland left Jones out was because he felt the game has moved away from a raft of scrums, meaning front-rows needed to bring mobility and explosiveness around the park.
Mathias can scrummage, of course. One penalty against the head helped move the Scarlets further ahead in their Challenge Cup round of 16 clash with Brive this year.
But he's a solid carrier as well. In the win over the Bulls this year, Mathias survived an onslaught from the South African's scrum - staying square to ensure the Scarlets kept possession. But, the icing on the cake was that he worked from the loose-head, around the corner, and forced his way over for a try.
It's probably a toss-up between Mathias and Corey Domachowski to be the fourth and final loose-head in Switzerland. Perhaps the Cardiff man edges that one as he's a more powerful scrummager, but it'll be an interesting one to keep an eye on.
Corey Domachowski and Keiron Assiratti
It makes sense to talk about Cardiff's props Domachowski and Assiratti as a pair, given they make up two-thirds of the 'Rhondda front-row' at the Arms Park alongside hooker Liam Belcher.
Both are fine scrummagers and that's where their strengths really lie. Against Sale this season, scrums against one of the strongest packs in England resembled mauls at times - such was the speed at which they sent the Premiership outfit hurtling backwards.
In that same game, Domachowski showed his eye for a line as he got over the whitewash for a score.
While, elsewhere in the campaign, Assiratti demonstrated once again how powerful a scrummager he was, driving Wales loose-head Nicky Smith off his own feed in the build-up to a try against the Ospreys.
In terms of how far these two go, Gatland has already spoken highly about them - so that's a good start. There's a decent chance both will still be there when the squad is reduced to 45 players and they'll be quietly confident of forcing their way in to the final shake-up.
Inexperience at Test level could count against both, particularly Assiratti. If Gatland does decide to go forward with Henry Thomas on the tight-head, it's unlikely another uncapped tight-head will be named too - even if Assiratti has arguably been in better form than either Dillon Lewis or Tomas Francis.
Domachowski probably doesn't have that same issue, providing he gets ahead of Mathias in the pecking order. However, Smith, Rhys Carre and Gareth Thomas are all established internationals ahead of him.
Henry Thomas
The Montpellier prop has been pretty clear about where his talents lie. While Thomas was at Bath, ball-carrying might have been his point of difference.
And he's solid in that area of the game, as demonstrated by this neat take-and-give against the Ospreys last year...
But after time in France, it's firmly at the scrum where Thomas believes he can make a difference. Certainly, tight-head is an area of relative weakness for Wales.
In that same Champions Cup clash with the Ospreys, Toby Booth's side put the pressure on the French club's pack early on - using Tom Botha to drive across into hooker Brandon Paenga-Amosa, forcing Montpellier loose-head Enzo Forletta to pop up.
However, Thomas stays low and square, allowing the French side to get the ball away under pressure. Crucially, a couple of minutes later, he has a word with the referee about how he'd stayed square unlike everyone else.
Towards the end of the half, he got his reward - earning a scrum penalty as Wales loose-head Gareth Thomas folded under the pressure...
There's a sense that Gatland hasn't plucked Thomas from France for no reason. He seemingly has big plans for the former England tight-head so a place right through to the World Cup seems the smart bet.
Will Davies-King
Young Cardiff prop Davies-King was another surprise name in this mammoth squad, with few - if any - having pencilled him in their predictions.
Having been exposed to Champions Cup rugby at an early age, thrown into games against Toulouse and Harlequins after Cardiff's squad members were forced to quarantine, he's slowly earned more minutes at the Arms Park.
This season saw him make 11 appearances, but only two of those consisted of 40 minutes or more of rugby. In that sense, it's perhaps surprising Gatland has opted to call him up.
This feels more like getting some things in place for the future, with Davies-King possessing the raw materials and now being exposed to the Test environment.
Certainly, he's had some testing experiences already. Those matches against Toulouse and Harlequins would have been a lesson, as was some of the pressure he was put under away to Brive as a late replacement this season.
Crucially, he never buckled under duress, doing his best to keep square when other props might have bailed or turned in. That kept possession for Cardiff, even if it was scrappy.
You never know, he could force his way in - but the young Cardiff prop is possessing longer odds than those he's up against.
Teddy Williams
The first of two uncapped call-ups to have already been in a Wales squad, Cardiff's second-row Williams has worked hard to develop his game over the last year or so.
For starters, he'll do the nuts and bolts you'd expect from a second-row, be it carrying hard, tackling anything that moves and even running the Cardiff lineout at times this season.
That lineout nous extends to often getting up in the air to steal opposition ball...
While he also showed some good support work throughout the season for Cardiff...
There's a fair bit of second-row competition, with Cory Hill back in contention and Will Rowlands fit again. As such, making the final squad might be a tough ask for Williams.
Max Llewellyn
Players would rarely see injuries as anything other than a curse, but for Max Llewellyn, an ankle injury might have just been a blessing.
Had it not been for that, Llewellyn could easily have been named in the Six Nations squad by Warren Gatland - given he's certainly the Wales coach's type. Had he been called up, then the impending move to Gloucester would have left him in the same boat as Joe Hawkins.
As it is, Llewellyn's maiden call-up came after he agreed to leave Cardiff, making him eligible until his first contract at Kingsholm comes to an end. As for what he offers as a player, the 24-year-old possesses pretty much everything you'd hope for in an inside centre.
Defensively solid, good distribution skills and subtle hands for his size. However, it's the lines he picks that really mark him out as Gatland's sort of player.
Given how suited he is to the hallmarks of a Gatland team, Llewellyn feels like an uncapped player who could certainly establish himself quickly in the coming months.
Joe Roberts
In the latter part of the season, Joe Roberts has become something of a crutch for Dwayne Peel's Scarlets. Starting virtually every game in the run-in, he offered an assuredness beyond his years at outside centre.
Sometimes, with 13s, it's easier to spot the bad ones than the good ones. After all, it's a position where things can quickly go wrong. One wrong defensive read and you can be cut to ribbons.
However, the 23-year-old has largely been solid in the Scarlets midfield since the turn of the year. There's nothing overly flashy from Roberts, but he just seems to do a lot of things well.
A willing carrier, he's capable of stepping in at first-receiver and directing a backline around the park, with his distribution decent thanks to being able to play inside centre as well as outside.
But it's defensively where's he a calm presence. In the last couple of years, the Scarlets' defensive line has resembled a faulty turnstile in its willingness to wave opponents through.
But Roberts reads the game well, stays connected, knows not to overchase and is capable of identifying a threat.
Against Clermont, he did a tidy job of shepherding the French side's dangermen, while the work to hold up Alivereti Raka from close-range comes from recognising that the ruck post, Mathias, has been sucked into the breakdown on the openside.
Beyond George North and Mason Grady, Wales don't have a great deal of options at 13. That should be enough to get Roberts into the 45-man squad for the training camps, even if the World Cup might come too soon in his fledgling career.
Keiran Williams
The hard-running Ospreys centre was another who was already part of Gatland's Six Nations squad, so the Wales coach will have a good idea of what he'll bring.
But just in case he didn't, Williams has continued to push his case since failing to make an appearance in the Six Nations. Against Saracens in the Champions Cup, the 26-year-old demonstrated just how dangerous a carrier he is.
In the build-up to the first try, he initially showed smart footwork, taking the ball deep and isolating Mako Vunipola in the defensive line with a late step...
What makes it so impressive is how Williams reads a slight disconnect between Vunipola as the 'monster' and his 'post' and 'guard' inside him. As 'guard', the defender inside Vunipola should be responsible for anything beyond the England prop's inside shoulder - allowing him to push and target the first-receiver.
However, there's just enough of a gap to sow a seed of doubt in Vunipola's mind, with Williams exploiting it by running hard at Vunipola's inside shoulder, sitting down the England prop, before stepping to his outside at the last second.
A few phases later, Williams shows more impressive carrying - this time picking a line off Owen Williams and exploding onto the pass to bump off Owen Farrell before giving the try-scoring pass to Michael Collins.
From the line he picks to how quickly he generates speed onto the ball - no easy feat to anticipate when he's third receiver on a pull-back play - there's certainly a lot to like.
Surely Gatland will want to see him in the settings of a Test match. Had injury not ruled him out of the Italy match earlier this year, it would have been the perfect setting for a first cap.
That will likely come in the warm-ups instead. With Hawkins no longer in the picture, Williams is well-placed to force his way into the 33-man squad.
Cai Evans
Ospreys full-back Evans had endured something of a frustrating season with the Ospreys. Before the end of 2022, he'd managed just 45 minutes of action. In January, he bettered that with 188 minutes of promising rugby.
As Toby Booth's side made it into the Champions Cup knockout stages, Evans looked assured - particularly in the home game against Montpellier.
Gatland had previously referred to Owen Williams' performance against the French outfit as being what earned him a Six Nations recall, such was the intensity of the European clash. Perhaps that was a factor in Evans' call-up.
Certainly, it wasn't about how often Evans turned out on the club scene, because he wouldn't feature again after the first month of the year. The likes of Johnny McNicholl, Ben Thomas and Angus O'Brien could all consider themselves unfortunate not to get in ahead of Evans.
So why did he make it? Well, the Montpellier factor seems to be the main reason, as well as perhaps what Gatland is looking for in a full-back.
The 23-year-old hardly pulled up any trees, but he was a steady hand on the tiller throughout. He was solid under the high ball...
He showed off his big boot...
And he showed a willingness to counter-attack on transition...
Wales' coaches often talked during the Six Nations about looking for attacking opportunities from kick returns and how they want to develop that.
Over the course of the tournament, they developed success in using Hawkins as a playmaking option in the backfield. It started out a little hesitant, as shown by the fairly flat options against Ireland, but improved as the tournament went on - with Wales getting around Italy's edge.
Maybe having another playmaking option - given Evans is a fly-half first and foremost - is some of the thinking there. Maybe it's just about developing options for the long-term in a position that Wales are desperately short in.
However, if you were looking at likely casualties when 54 becomes 45 before the trip to Switzerland, Evans would probably be one of them.
