Looks like Twitch pulled the trigger a bit early on some new Watch Dogs 2 ads. The new ads seem to show off a weird teaser for the new game. Also according to this and other leaks, Watch Dogs 2 will be out on November 15. It will be set in San Francisco.

Twitter user, Fobwashed (whom you may know as the guy that makes games and creates a lot of gifs for Giant Bomb), managed to snag the video ad before Twitch realized their boo-boo.
Don't worry though, I'm expecting plenty of additional Watch Dogs 2 coverage soon. Ubisoft apparently sent Watch Dogs 2 "gifts" to various YouTube "personalities." I'm sure they'll sufficiently hype it up no matter what.
