IMO, Nintendo would still be better off if they ditched the console business and focused on games. The unique control devices like the Wiimote and the WiiU tablet thing are nifty, but I feel they're at best a gimmick and at worst a significant downgrade from a normal controller (Metroid Prime 3, I'm looking at you.)

There's nothing they can do on their own console that they can't do on someone else's. Zelda or Metroid on a PS4 would be awesome; and while I'll still probably buy a WiiU once those games come out, I'd also buy them on a PS4 or Xbox One. Unless Nintendo makes a whole lot of profit on the WiiU, they're not coming out very far ahead considering the large expenses involved with designing a console.
