I know I keep saying this, but Nintendo is really going to have to buy support. Sure, they can't turn every Tom Studios, Dick Games, and Harry. . .Arts? in to Retro, but they've got to fill in the gaps. I can see Nintendo getting 3DS support from Squeenix, but not Wii U.
A Tales game is likely. Maybe they can dig up PowerStone? That'll put two great, exclusive fighters on the Wii U.
