My mind hasn't changed, I just fancy England even stronger now. I can only see England winning it, they actually played well and were slightly unlucky losers. They will come on bundles for that game and improve.
By process of elimination:
Wales are injury ridden and will struggle
SA currently aren't good enough, e.g Japan result
France just are not good enough
Ireland are overrated and have a dire record in this
AUS are hit and miss and blow hot n cold, don't fancy them
NZ are bottlerrs / chokers and can't win outside of NZ
Although it is unfortunate, I do think the injury situation has been overblown to some degree. Wales's game plan revolves primarily around the forwards at the moment, all of which are fit and available. The forwards is also where Wales have the most strength in depth - there are multiple positions where players are fighting for starting spots i.e. Owens/Baldwin, Lee/Francis, Charteris/Davies, Lydiate/Tipuric. I think this healthy competition between players is one of the reasons this group of forwards has been putting in such gutsy performances. For the Fiji clash, Wales have multiple possible options with the forwards, perhaps bringing Jake Ball into the mix for some attritional play, or Moriarty for the same purpose. So even the forwards who will definitely not get a starting place against Australia still have a purpose to play and the strength in depth is there.
With the backs, Davies has been great so far and Lloyd Williams is on form too. Biggar is Biggar, but Priestland hasn't been great. Roberts is crucial to our game plan and an injury to him would be very costly. Outside centre is now Wales' biggest concern, but if North does slot in it's good to know he has played there a bit now. The back 3 is the biggest concern, but there are still plenty of options in my eyes. Morgan is an attacking threat at wing or fullback, Priestland could play fullback (though I wouldn't want this), Eli Walker could potentially come back in, North may well stay on the wing if Tyler Morgan gets brought back in, not to mention the likes of Jordan Williams, Kristian Phillips, Harry Robinson, Rhys Patchell, James Hook, Tom James, Dan Evans, Hanno Dirksen, Richard Fussell and Dan Fish who could be called upon. So personally, I don't think Wales' strength in depth is too bad. I mean, if worse comes to worst they should just stick Lloyd on the wing again, seems to know what he's doing
