They will be on both. it will first come out on PS2 but because the PS3 is coming out so soon square enix thought it would be a bit odd to be carry on making FF games for PS2, so it will be released on both. I would think that the graphics or something would be enhanced a tiny bit as the PS3 can play PS2 games anyway and so it would be pointless to not make any enhancements. I am not sure when it will be released for the PS3 though.
