I don't know if S-E left content out of the game because of X360 but I really don't see how this debunks that assumption. Game content (whole FF map) is still 6.8gb (limit of X360 Dual-Layer DVD) and If I am correct every disc contains whole FF world. With compression they obviously take couple gigs away but still we have something like 4gb data to be repeated on every disc so there is about 3gigs of space to fill with compressed cutscenes. S-E's target was 3 DVD's so maybe they left some content out that they thought was unworthy or maybe they didn't. This is just speculation as long as S-E says something about the matter and probably they won't.
