When you are Batman it is pretty safe to say that you know a thing or two about your own game, so when legendary voice actor Kevin Conroy let slip that Rocksteady's upcoming Batman: Arkham Knight was coming out January 2015 you better believe the Bat is right.

Conroy mentioned the date in a recent interview at Denver Comic Con with GrooveyTV, stating "I have a massive game you may have heard of called Arkham Knight (at the 5:10 mark) "It was supposed to come out in January, we've been working on it for a year and a half, it's still not done. So it's going to come out next January, but I know everyone is frustrated."

Batman even has a reason to why Arkham Knight was delayed from its original October 2014 date; "The reason it's been delayed is because it's so awesome."

The date slip up hasn't been officially confirmed by publisher Warner Bros. Interactive Entertainment, though here is hoping Batman is right. Batman: Arkham Knight will be launching on PC, PlayStation 4 and Xbox One, and if you missed E3 2014's Batmobile gameplay you can check that out below.
