Warner Bros. Interactive Entertainment, the publisher behind the Batman Arkham franchise, has teased a new franchise-related announcement for the 31st of December, 2013.
The image that supports this story was posted on the official Batman Arkham facebook page, but nothing else was offered to suggest what this announcement could be related to. Therefore, it could be something simple like new downloadable content for Batman Arkham Origins, or it could be something much bigger. Who knows, Warner Bros. may even choose to announce the next generation of Batman games, which we can assume Rocksteady Studios are already hard at work on.
Either way, we'll see you on New Year's Eve, when hopefully all will be revealed.
