Be careful what you wish for I'd say. Square Enix may be making the games, but Disney actually owns the majority of the series. If I remember correctly, they even own Sora and the other original characters despite Nomura designing them. Hence, you probably will see a KH movie, TV series, etc., at one point in time. Don't be at all surprised if Nomura and Square aren't involved though. Be even less surprised if it sucks so bad it all but kills the series, either.
