Well if PS2 were dropped, we could maybe have an actual expansion with new zones, art, story, graphical engine upgrade, auto-translate update, and so on.

Hard to do tho due a lot of Japanese ppl still play on PS2 and other ppl around the globe. They would have to do something to convince ppl to move to new systems, like a PS3 downloaded version or even some type of discount with Sony on PS3 or something.
