The news came not through the usual games industry sources, but as part of a call to investors by Time Warner's Chief Financial Officer John K. Martin. Talking up the success of the media giant's gaming arm, he told shareholders that "we also have a strong games release this year, which will include the next release in the Batman Arkham franchise."
While that nugget may have been of only passing interest to the money men on the other end of the call, it's a pretty big bombshell for gamers, with the Arkham series being one of the most popular and successful superhero adaptations of all time. There's no further information on what form the game will take, or when it will be released, although the previous games launched in August and October respectively.
Rumours persist that the third game will be a prequel, set in the colourful comic book Silver Age, and will find Batman working with members of the Justice League. Warner Bros, perhaps wisely, is keeping quiet on the details.
