Batman: Arkham City is getting a follow up later this year, as confirmed by license holder Time Warner's investor call last week. Seems it went under the radar.
The full transcript of the investor call can be found via Yahoo! Finance.
During the call, Time Warner's CFO and chief administrative officer John K. Martin stated, "And we also have a strong games release this year, which will include the next release in the Batman Arkham franchise. So all in all, we expect Warners to post another very strong year in 2013. And with a little luck, the year should be as good or maybe even a little bit better than 2012."
VG247 own sources confirm that Rocksteady Studios is not developing this particular game. This could nod to the rumoured 'Silver Age' Batman prequel that was touted last year.
This could mean a new game in the 'Batman: Arkham' franchise is due before the end of the year, or as part of the next financial year. We've contacted Warner Bros. to confirm.
