Disgaea 3 - Comes out tomorrow. If you like SRPGs, then this is a must have. The Disgaea games are very fun, but they are pretty long. Make sure you have lots of time to devote to it.
Eternal Sonata - Since you have a 360, I'm pretty sure you've played it. The PS3 version comes with extra features/content. If you enjoyed the game and care about the extras, then get it. Should come out before the years end.
Valkyria Chronicles - Looks pretty amazing. The graphics, combat system, etc. So far, it has gotten lots of positive previews and reviews.
Folklore - While it isn't an RPG, it does have some RPG elements. You'll admire it's storytelling. Definitely hooks you and leaves you wondering what happens next. The gameplay is pretty fun; each folk has kind of their own ability. Try and catch them all.
White Knight Chronicles - Level-5 games are pretty great, but they sometimes lack a good story. Jeanne D'Arc proved that they can deliver a great story. Hope they do the same with WKC. We'll probably get a release date on TGS.
