After sifting through coding for Capcom’s big budget crossover, locked away content was found; content that had originally been announced for Fall’s PS Vita edition of the game, and implied to be DLC.  We’re not only talking costumes here.  There are a total of 12 additional fighters to play as hidden on-disc, and Capcom says you’ll have to pay for the pre-made content to put it to use.

“The playable characters will make their debut on the PS Vita system when the game is released this fall, with the console and PC versions receiving them as DLC soon after. The character information and files were intentionally included on retail versions of the PS3 and Xbox 360 game to save hard drive space and to ensure for a smooth transition when the DLC is available, allowing players who choose not to purchase the content the ability to play against players that did.”
