While Rocksteady Studios has not locked down a final resolution or frame rate for 2015's Batman: Arkham Knight--the "ultimate Batman simulator"--the developer now says it's aiming for graphical parity across all platforms. The reveal came as part of a recent livestream when Rocksteady Studios was asked specifically about the resolution and frame rate for PlayStation 4 version of the game.

"We don't know yet," a Rocksteady developer said. "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."

Arkham Knight is the third game in the series from Rocksteady, following the original Arkham Asylum (2009) and Arkham City (2011). Last year's Arkham Origins was developed by Warner Bros. Montreal.

The game was originally targeted to launch this fall, but publisher Warner Bros. delayed it to 2015. The game is now scheduled to launch in June 2015 for Xbox One, PlayStation 4, and PC. Batman superfans and collectors might also be interested in a $200 Arkham Knight special edition that comes with a model Batmobile.

Arkham Knight is one of the many 2015 titles Sony is showing off during its PlayStation Experience event in December. For more on Akham Knight, check out GameSpot's previous coverage.
