Okami, Valkyria Chronicles, actually a lot of JRPGs. it's a genre I want to try more of, even though I don't have very favorable opinions of the Final Fantasy games I've played, but an awful lot of the ones I hear good things about are PS3 exclusives or whatever. Oh, and I hope Bungie gets around to doing a PC release of Destiny, I think it looks neat.
Oh, and more Ace Combat, like someone above said. I didn't really like a lot of the changes they made in Assault Horizon, felt like they lost what I liked about the other entries (cool superweapons, sprawling battlefields, alternate-earth storylines; all in the name of call-of-duty-ifying the game with turret sections and flashy setpieces.
