Mass Effect 2, perhaps. If they've changed the inventory system to something not awful and let me have an army of Krogans. :P

Elemental seems like it has potential, dunno if I'll get into it or not.

Halo 3: ODST simply becaue it has like half the cast of Firefly doing voice acting - though I will likely piggy-back off a console gamer friend instead of actually buying it (and the xbox to go with it ).

I don't really know anything off the top of my head that is coming out that I'm really excited about. HL2:E3 + another TF2 pack would make me very happen, but I'll probably old by then. (:P)
