I'll mention there is some talk beyond the plateu but not specifically.
It's just a bit hard to go into details about some things since that would go into deeper spoilers to explain more. The thing is the game is fantastic, I expect it to score well and most will probably love it, but it's definitely not flawless. Its three biggest issues as far as I can tell are the following:
-Technical problems (this is definitely worse on WiiU than Switch, but Switch does seem to have some noticeable frame rate drops too). Frame rate on the WiiU drops fairly regularly, sometimes as low as to 5-15 frames. This isn't just something tech geeks will notice, it's incredibly noticeable. Also there's some TERRIBLE pop-in on the WiiU, sometimes as bad as a character not popping up until they're literally two meters in front of you in some of the most extreme cases. I hope that's better on the Switch.
-Voice Acting. This is in terms of the English dub, I don't know about the other dubs. It's really hard to talk about this one without going into specifics but I am lead to believe going more into this a big part of the problem was the voice directors. Some characters are fine or good, but some are really just awful. There's some scenes that are meant to be emotional, but it would've been more emotional if it didn't have voice acting because the delivery being done is just terrible. I can't go deeper into that or which characters or what because of spoilers, even the clip I posted earlier was just the next voiced bit that popped up on stream I managed to record briefly and hardly the worst example of the voice acting or anything. In some parts the voicing is good, don't get me wrong. But the voicing has some parts where it has bad delivery, forced put on voices that don't even sound cartoony they just sound bad, but the biggest issue is that it's not just bad voicing by itself, it's bad voicing which actively takes away from moments in the story. Many not hearing the voicing will probably want to believe that it's okay and subjective, and in some cases it is, but there is some legitimately bad voicing going on here and I'm sure you'll see this creep up a lot because it really stands out when the game is trying to do a deeper character moment and the voice either doesn't fit, is so bad it's funny, is legitimately cringe-worthy, and takes away when the game is trying to be story focused. It's a bad sign when a big cutscene is coming up you almost are hoping it's not voiced. Zelda can work with voicing, but I think they dropped the ball here quite a bit.
-Big open areas. This again is harder to say without going deeper, but since some people touched on it I will... This game has some of the staples of other big Sandbox games, and not always in the good way. It does have large empty spaces, it has literally the 'ubisoft' towers if you know what that is, and it's weird to see other open world game's problems turn their head in a Zelda title. And the thing that sticks out more is that much of this often doesn't even have Zelda charm to it, it just feels like they put in some of these big open spaces and elements because other sandbox games were doing it. It's not a game killer again, but I think it's definitely noticeable just how barren a number of places on the game map actually are.

But while all three of these things I think will be criticized by many, and rightfully so, they don't ruin the game. The game itself is fantastic in many ways, it has some interesting changes to the Zelda formula but in many ways feels like changes they needed and they got really creative with. There is a game more than worth experiencing here, these flaws aren't game breakers and the game seems really enjoyable despite these issues. But that's the thing, it's in spite of these issues, these issues are definitely noticeable and I don't think are exactly minor. But it's not like the game is bad, quite the opposite it's quite good, but its flaws are really noticeable but I think most everyone will still really enjoy the game in spite of the flaws.
Some thoughts I'll throw out there, don't worry it's not like the game is ridden with issues, it does a lot that it does extremely well and has a lot of memorable moments, elements, and captures a lot of what I think they were going for with the world. These things are just kind of blemishes on an otherwise very good game.
