What ? i ignored no one, i just can't answer to everybody, and i'm far from knowing all
I already touched upon that many times before. It will mostly rely on third-party, i don't think the hardware gap between the systems will be so much groundbreaking that either Wii U is condemned to not see ports of PS420 games because of a technical impossibility, either PS420 titles will be deprived of the use of shiny new features because the Wii U will be the lead development platform (like PS2).
From the few i know of the next playstation and xbox, they are really beasts, but not a leap in feature-set, in generation, like if the Wii U would have been a "directx8" system and PS420 "directx11".
Now, there are still some hardware questions, like the GPGPU that could be the next big thing like Crytek think, is the heavily customized Wii U gpu will be as capable in regard to that as PS420 ones for example ?
