I think he means the very beginning of the Organization XIII, years before Roxas and Axel joined it. From the looks of it, I don't think KH3 is a prequel but rather a continuation of KH2. I hope Marvel characters or better, The Princess and the Frog w/ Tangled, would included in the game.
one in bold= unlikely. but I would love the two movies you mentioned in KH3. but it better be PS3 exclusive or the whole KH fanbase will riot and go berserk. :sweat:
