Explosion:" The release date for Batman Arkham Knight has again been delayed. Fortunately, right after the announcement of the latest delay, Rocksteady Studios was nice enough to release a new extended gameplay video to tide over fans. It was a smart strategy. Rocksteady softened the blow of the delay with the release of the new gameplay footage. The release claims that the new video features footage that was captured directly from a PlayStation 4 system, and not a dev kit.
