The interesting part? Conroy let slip that Arkham Knight is set for release in January next year.
“I have a massive game you may have heard of called Arkham Knight. Have you heard of Arkham Knight? … a little indie game. 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,” says Conroy at around the five minute mark.
Arkham Knight was indeed until 2015, so Conroy could be accidentally revealing a real date here. Of course, without any confirmation or denial from Rocksteady this is firmly in the 'unsubstantiated rumour' category right now.
We'll get back to you with any official response. In the meantime, check out the recent Batmobile-heavy gameplay trailer and hope that January date is correct.
