I say this as a fan of XIII and XIII-2: I hope this is the last game in the Lightning/Serah/Cocoon/Pulse/etc. storyline. Not because I haven't liked the games, but because I want this game to have the ending that everyone has been wanting from the start. You know... one that ends, and makes vague amounts of sense. Given that this is a Final Fantasy game, though, I doubt it'll make too much sense.
