Things have been suspiciously quiet since Rocksteady's last entry in the Arkham franchise, Batman: Arkham VR landed in 2016. Since then, fans of the games have been speculating on what Warner Bros. Interactive and Rocksteady are cooking up next, with the most common theory being that they're planning on doing for Superman what they did for Batman and finally make an unambiguously great game about the character. It was widely assumed this would be unveiled at E3, but that came and went without a peep from the publisher.
