Square-Enix held a concert in Japan recently celebrating Kingdom Hearts music. At the end of the show, Nomura appeared on stage to announce story DLC for KHIII which will serve as KHIII's version of the Final Mix releases of previous installments. No date was given for the release.

It will feature more story scenes in the game, secret episode, and more bosses. Japanese players will also get the option to switch to the English VA.
