I doubt this will happen, but if they're not releasing the newest game on the Wii U, then it'd be nice if a few months after releasing the newer versions on the PS360, that they release an updated roster patch as either free or cheap DLC that Wii owners can download if they wanted to.
I say a few months after because obviously they want to make their sales with the new games being $60 each. After a few months there wouldn't be any sort of loss.
Maybe Wii U owners who own NFL 13 should go campaign about this on the EA forums. It shouldn't be difficult to patch in the new roster and if they sell it as cheap DLC, they'll still be making something off it.
