IMO, Nintendo's future lies with the 3DS. Handheld gaming is what most of their franchises are opimized for, especially now considering that Smash Bros is going portable too. Who knows, maybe they could make a good 3D Zelda game for handheld. If they could, they could just go straight handheld, and there's something to that. From a business standpoint and a fanbase standpoint it would be a horrible decision for Nintendo to make, but I think the big N could survive if the Wii U goes Dreamcast. Which it won't.
