With the new Rocksteady game coming out in 2015, Batman: Arkham Knight is expected to have the same frame rate and resolution on both the PS4 and Xbox One. “We’re about six months away from going gold. So we don’t know what the resolution and the frame rate’s going to be yet. That’s something that happens during the optimization phase of the game. We’re aiming for parity across all platforms. Whatever it is, it’s going to be awesome.”
Batman: Arkham Knight was slated to release this fall, but it was delayed until June 2015.
