Games built FOR the Wii-U will run at 1080P such as first party and 3rd party exclusives.
But since MS and Sony will be launching after Wii U, their consoles will be more powerful than Wii U (though a smaller gap than this gen).
So games built for 720 or PS4 and ported to the Wii-U will have to be down-scaled for Wii-U since it won't handle the exact same things those consoles can. You know, kinda like games that can run on PC this gen are down-scaled so they can run on PS360?
Why does no one seem to understand what I'm saying?
i really doubt that they'll need to down scale them selves in order to run the multi plats
