That unused Luna theme is amazing though I feel like it played during a Luna and Ravus scene, specifically the one in Altissia. Could be wrong. As for the FF theme I prefer the version they went with in the main game though this one is nice too.
it reads "Fabula Nova Crystallis" on the red card, and i think "Etro" on the first one (yeah each one has a different mark, first is Etro, second Pulse and third Lindzei, all written in their respective alphabet); this is the same deck of cards used in XIII-2.
funny that the lady in white (guess that's one representation of Etro) is so alike to ghost Luna.
here's a possible translation for each card if you're interested.
Funny, what next 'unused\cut' thing people will post in youtube\reddit. Im waiting those pirates to announce that they cracked completely this game before lanch.
I hope this situation will show SE that better stay at console
