It has now been officially confirmed WB Games Montreal will reveal their long-in-development game at DC FanDome on August 22.
After much teasing over the past several months whatever Warner Bros. Games Montreal is working on will be discussed during a panel in the middle of the day where the new video game — rumored to be Batman: Gotham Knights — will officially be announced.
The full schedule for the event has been released and WB Games Montreal will have a special announcement of a new game and a Q&A with developers. Given the 20-minute length of the panel they could slip in a trailer or teaser.
