Blue Dragon disc hiding secrets?

Remember how Microsoft said there was going to be downloadable content to add in a new game plus mode for Blue Dragon? The download appears to be a 204KB key to unlock items already on the disc. The content is free so it’s not like Blue Dragon is leeching extra money for new modes, but Microsoft did release the patch three months after the game’s release. Why? To increase replay value and to get people playing their Xbox 360 again even if it’s Blue Dragon for a second round. Since new game plus was a nice surprise, could Blue Dragon have more surprises like extra sidequests or monster hunts?
