UPDATE!  Here is the game play trailer!

Batman: Arkham Knight was one of the domain names registered last year, according to GameInformer‘s list, alongside Arkham Origins. A quick check of the domain on WhoIs.com shows that it was registered by the same agency as the past titles in the series, and that they updated the domain on December 10, 2013.  Two sites have reported this, the first being Newsarama and the clincher being Bleeding Cool‘s confirmation.

More on Batman: Arkham Knight is expected tomorrow when DC’s All Access Tuesday goes live.
