I played Eternal Sonata on the 360 and i loved it. It's a good JRPG to add to your collection. Also, Tales of Vesperia would also be a great game, but It's not release to PS3 yet (I played it on 360). It has more features than the 360 version. Fully voiced is one of the feature (damn if only 360 had fully voiced too :()
Edit:I too am wondering what RPG is there for PS3 since I've decided to buy one later on in the future.
