They've announced the Sazh Story DLC. It's 400 points which is interesting, I'm guessing it's not going to be too long for that price. There's some secret DLC and two costumes coming but I don't care about them.
I'm guessing the secret DLC is another Coliseum battle, I think you'll probably be able to recruit Sazh at the end of his episode and the coliseum battle will be against Jihl or possibly Snow and Hope I think.
