After the Vita version was announced to get 12 new characters by default, many gamers wondered what fate would befall console buyers. This question happened to be answered by some hackers on the Xbox version. It would seem that the character data for most of the DLC characters, is on the disc. The same goes for their prologues, endings and other such things.
While nothing is really known past they’re there and usable, it wouldn’t make any sense for them not to be included at some point. Naturally this could piss off many fans, though I would like to remind you that these characters have YET to be detailed. Because of this, they could also be free downloadable content down the road. Sure its unlikely, but it’s best not to jump the gun quite yet.
