It was announced yesterday by Namco Bandai Games Europe that they are currently working on a DLC pack for the PS Vita edition of Dragon Ball Z: Battle of Z which will bring a full Japanese dialogue track to the game. No release date has been set for this DLC pack but the one piece of information that they have confirmed is that this add-on will be available completely free of charge!
We’ll let you know more as soon as we get details of a release date.
