You should wait to see what SE reveal at the Tokyo Game Show. I believe they have announced that they are building up a franchise on the Xbox360, so we'll see what else they have to offer. That is if you are worried about RPG's coming to Xbox360.

I don't know anything about Lost Odyssey to be honest -- I haven't been following any PS3, Xbox360 or Wii stuff at all. Infact, Bioshock for PC is the first next-gen game I've played.
