The next installment in the Assassin's Creed series may be pirate-themed or at least set on the high seas if a poster sent anonymously to Kotaku is genuine, as it shows our friendly neighborhood assassin cavorting with some scurvy swashbucklers on the deck of a sailing ship with the caption: Assassin's Creed IV: Black Flag. We shouldn't have to wait too long to find out whether this is true, as Ubisoft recently announced the next installment in the stealth/action series will use a new setting and is expected to be released between April 1, 2013 to March 31, 2014. Further, Kotaku says their tipster says this poster is to appear in stores beginning March 4th.
