After playing most of the games mentioned so far in this thread, I'd have to say that the New Super Mario Bro's is my most anticipated title, followed of course by Mario Kart. Meteos is already a done deal, pre-ordered from EB and it arrives tomorrow. :-)
Still really waiting for a good strategy and RPG...we'll see how Lunar and Age of Empires turn out.

P.S. MrMojoRising: we don't mention THAT game, ever! **shudders**
