1. Super Street Fighter IV
I love SFIV, can't wait for the sequel. Will probably buy this day one regardless of what I hear.
2. Tom Clancy's Splinter Cell: Conviction
Just looks like a really cool action game. I've never really played stealth games before but this one makes me want to.
3. Just Cause 2
This game, based on the videos I have seen, is going to be CRAZY FUN. Or, it will totally disappoint. Hopefully it's the former.
4. Final Fantasy XIII
I was a huge fan of FFX, and now that FF13 is coming to 360, I can't wait to play it. Really the only RPG I'm looking forward to right now, sadly.
5. Mirror's Edge
Although the first one wasn't critically acclaimed, I really enjoyed it. It was a nice change from all the shooters and the visual style was cool too. Hopefully the sequel improves upon it.
