They are not sure if it's the episode which expands on the ending of the game, but apparently features a different battle system,
Confirmed just after Jhil in Coliseum did.
In addition to the recent announcement regarding Jihl Nabaat DLC for the Coliseum (available March 13th on PSN and Xbox Live), we also are happy to announce that new story DLC will be available featuring Lightning and Caius!
The new “Lightning’s Story: Requiem of the Goddess” story DLC will feature Lightning with her battle against Caius before unseen to players. This new story will be available mid-May.
Also don't forget that new weapon DLC for Serah and Noel, including the infamous Muramasa has just gone up on PSN and Xbox Live. Get yours today!
Might get this but the Sazh one was a let down unless I just got bored of playing cards and more actually happens lol
