Nintendo needs many kinds of IP.
One is a high production RPG with Square Enix or MistWalker's Quality. Of course we will get ToS and will be successful, but we need a more "mature" RPG to prove that the genre can live very well in that platform. This is why I believe Nintendo bought Monolith Soft, because they have no experience in RPG except in SRPG like Fire Emblem and that's a completely different kind of game.... (I think this is why SE is delaying Crystal Bearers because they fear this could happen and need to get ready).
A driving simulator will be less likely to happen in the short term, their experience is in arcade racing and they are good at that (Please give us F-zero for Wii, Nintendo). They need a company with experience.
An RTS game. with Warcraft III quality (obviously with simple controls but the remote and nunchuck have potential on this).
