In terms of sequels, I'm looking forward to No More Heroes 2 and Monster Hunter Tri the most (even though it will be my first Monster Hunter game ever). I just hope they're not released too close too each other, as I will likely have to pick one over the other, and that's gonna be a tough choice.
EDIT: How on Earth did I forget Super Mario Galaxy 2? That beats both of my other choices by miles.
