While the “oops” has since been removed from Facebook, NeoGAF was quick as can be with the old print-screen button on the keyboard, and has posted the shots.
According to GAF, a Flash file containing the logo and Altaïr’s name in Arabic script popped up, and a post on the page states for folks to click the link to help reveal an “exclusive look at the upcoming Assassin’s Creed game.” According to GAF, the Flash files are still present on Ubisoft’s server.
Ubisoft said previously that the next Assassin’s Creed game was to be revealed in May, so it’s possible that someone just pushed the button a bit too soon on the old Facebook.
The next game in the series is expected to be released during the Ubisoft's fiscal year of 2012
Ubisoft announced its E3 press conference for June 6 yesterday so be prepared for a reveal this May.
