Super SF4 is actually Q2 (April 27). I've already got Bayonetta, Mass Effect 2 and No More Heroes 2. Getting:
Yakuza 3
Final Fantasy XIII
Mega Man 10
Perfect Dark XBLA
Pokemon HeartGold
SMT: Strange Journey
Resident Evil 5 DLC
Sakura Wars, eventually
NeoGeo Battle Coliseum, Metal Slug 7 XBLA, and After Burner Climax if they're out
Not sure about:
Shiren the Wanderer
Monster Hunter 3
Bioshock 2
I'd also like to get Espgaluda 2 next month, but that doesn't seem likely at this point. I think all those games are Q1 anyway, haven't payed much attention to delays outside of Lost Planet 2 and Super SF4.
