Recent changes on the Batman: Arkham City Facebook page, as well as the total obliteration of the Batman: Arkham Asylum page have prompted speculation that the new Batman: Arkham game will be revealed sooner rather than later. The title of the Arkham City Facebook page has been changed to simply, Batman: Arkham, implying that the rest of the subtitle will be revealed when the game itself is revealed.
This is all in line with recent announcements confirming the title’s ongoing development. Further rumors have suggested that Rocksteady is not involved and that it is being developed by Warner Bros. Interactive Montreal. Paul Dini is also confirmed to have not been contacted to write the game’s script.
