LEVEL-5 have confirmed that they will release downloadable content to support Professor Layton vs. Ace Attorney.
Before you worry yourself unnecessarily, this will take the form of an unedited script of the original story by Ace Attorney writer Shu Takumi, that will be accompanied by a gallery of outtakes.
Professor Layton vs. Ace Attorney is only currently confirmed for release in Japan on November 29th.
