Would be cool if you have to do it without killing him or you automatically lose. Lots of interesting possibilities!
Yoshida stated there's 2 big spoiler bosses in Final Coil. I anticipate Turn 12 will be Louisoix under Bahamut's control and Turn 13 you will fight Bahamut himself with help from Louisoix. I really don't see what else it could be with 2 story based bosses in there.
