There is to be another chapter in the long running Batman games with yet another Arkham game to be released this year. Yahoo Finance published a post on a Warner Bros Q4 2012 investors call.
There isn’t any news on whether Rocksteady Studios will be involved in the development of the game. Fans will have to wait either sometime this year or early 2014. We will have news on this story as it develops throughout the course of the year.
