I mean, everyone keeps saying "Nintendo will show how it's done," in terms of pushing Wii U's graphics, but really, will they?
So far they've shown no inclination to. New Super Mario Bros U looked like an up-rezzed Wii game, Nintendoland was pleasant looking but simplistic, Pikmin 3 suffers from Twilight Princess Syndrome with beautiful effects but textures that look like holdovers from its beginnings as Wii game.
Is it so hard to imagine that Nintendo, which tends towards simpler visual styles and is new to HD development, simply won't both pushing the system? Hell, they didn't even bother pushing the WII most of the time, and pushing Wii U will likely be quite a bit harder and more demanding.
Then there's third parties. It's unlikely multiplats will be optimized to take advantage of Wii U's larger RAM and newer GPU. As for exclusives, games like Wonderful 101 and Sonic Lost World, are following Nintendo's lead and using simple styles that don't require a lot of technical omph.
So far we've seen only ONE game, X, that hints at the system's visual potential.
At this stage I can just see E3 drawing to a close with nothing shown that doesn't look like a 360 port. (Or worse, a Wii port)
