It looks like a Wii U game. Which is to say, it looks fine for the hardware. As far as flight games go, I've seen way worse on Xbox 360.
So it doesn't look "amazing", because the Wii U isn't capable of that. But it also doesn't look "outdated" because, by the standards of modern Wii U visuals, it is perfectly fine.
I've always found the complaints over the graphics, in particular the comparisons to GameCube and N64, to be absolutely ridiculous. Anyone making that comparison has never played those systems before. I would also extend that to anyone comparing this to an early Xbox 360 game: as someone who owned one at launch, I can say that everything I've seen of this game blows those early 2005 HD games completely away.
That being said, the visuals certainly seem to suffer from having to render the game twice on two screens. Star Fox Zero shouldn't be an average looking Wii U game, but the BEST looking Wii U game, because it isn't being tasked with rendering wide open areas. Still, the complaints over the game's visuals are greatly exaggerated in my opinion.
I'm not going to be saying anything else on the subject until I'm playing the game on my own TV screen. That has always been the best way to judge a game's visuals.
