we might have the sequel to : final fantasy 13 before the year is over, since it wouldnt take that long . since all the assets are finished , i think its more likely to come out though sometime in 2012 .
tales of graces f might come over here, thats still under consideration as far as i know from namco.
we could also have some rpg's in a hd combo pack like gow and sly cooper, i think at e3 will should have i say about 5 more at least added to the list that @stokedup was nice enough to prove us. :)
also legend of dragoon might come outside japan on psn in the ps1 classics like it did in japan.
so the ps3 should have a pretty good year of rpg's, which makes me a very happy gamer. :)
