I don't expect much difference between the ps3/360 and Wii U versions, except for the tablet support and better frame rates. The later will be implemented only because it will not cost anything to the developer. Still, considering TV sets are bounded to 1080p and 60 fps and textures are limited to the size of the memory, I think the Wii U will hold its ground nicely against the next consoles by Sony and Microsoft. Just look at the best looking PC games of the moment. The Witcher 2 and Battlefield 3 looks much better at the PC but not fundamentally different from their console counterparts.
