The Assassin's Creed Facebook page shifted over to the "timeline" display today, choosing that mysterious snowy image for its panorama.
On cue, Ubisoft's page managers followed up with a comment that "a major announcement from Assassin's Creed is only days away," yet also advising folks to check the official Assassin's Creed site tomorrow.
Don't believe for a second that image isn't deliberate. Now, as for what snow has to do with Assassin's Creed III, who can tell. But some good old-fashioned rumor and speculation has this set in the New World—i.e. America, likely around the time of the American Revolution. For decades schoolchildren have read of the Continental Army suffering in the cold at Valley Forge, and Gen. Washington crossing the icy Delaware River.
