[UPDATE] This has been proven to be false by several sources.
At the DC All Access Panel at Wondercon, the trailer for the next Batman game, Arkham Knight, was shown. It featured the voiceover of Thomas Wayne reading his last will and testament. After the trailer ended, they told the audience that Batman: Arkham Knight is no longer a 2014 project, but a 2015 project. We are waiting on a response from Rocksteady about when the game will be released, so make sure to check back on NextGenerationGamer to get all your gaming news first!
