In any event, there is one surprise I've been hoping for... a new console Pokemon game. Preferably more akin to Stadium/Stadium 2 or Colosseum/XD, and NOT like Battle Revolution. I would flip out if they announced they had plans to do one... though I'm not holding my breath, I'd anticipate them waiting until X and Y are more established first.
Though I'm also curious if we might see titles from some of the other games features in Nintendo Land; i.e., F-Zero or Takamaru. Unlikely as it is, it would be a nice surprise.
