The scene halfway in the game where Caius says the stuff that Noel remembers at the end of the game was on my mind since I saw it, made me wonder how SE would pull this one off, since you couldn't win either way if it were true. I was actually happy to see SE had the balls to match it in the ending. I was beginning to fear they would pussy out before that moment (battle included) and it would be added in that "proper ending" DLC.
The whole game had a "can't escape fate" vibe for me. Where Fang and Vanille defied "fate" with their little pillar only to see it destroyed centuries later, Caius' speech halfway and all sorts of other things made that vibe very strong for me. So I was actually happy with this ending.
