I'd love to see a new IP. Given Miyamoto's recent comments about F Zero, I don't think an F Zero game is in the works anywhere at Nintendo, but might appear in the next few years.
If it's not a new IP, Starfox or Metroid are quite likely. I agree with others, though; the launch of Wii U is a great time to launch a new first party IP and give it maximum exposure.
EDIT: I'd like to see Retro co-develop the next Zelda after their launch title, really, and assuming that doesn't take a ridiculous amount of time, then return to Metroid or resurrecting an old IP.
