Treat this as rumour until the full report comes out, but over on the Batman: Arkham City forums a user posted what he claims to be a quote from the Time Warner financial statement.
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.
