Assassin's Creed 4 next-gen release date, trailer leaked

A slip up on the new Assassin's Creed 4: Black Flag website apparently gave away the next-generation title's release date.

"Also coming to next-gen systems," some accompanying text advises. The initial announcement mentioned only PC and current generation consoles.

AGB has posted what appears to be a still from the trailer:

The page also mentions a Todd McFarlane poster as a pre-order bonus.

Assassin's Creed 4: Black Flag has been leaking like crazy for several days now, and Ubisoft confirmed its existence with a countdown site this morning; the page other sites report seeing will apparently become accessible once the countdown ends.

The October 29 release date may give us a clue as to when the PlayStation 4 and Microsoft's new console will release, although it's possible Ubisoft will release current-generation versions ahead of their next-gen brethren.

GamesRadar has the leaked trailer posted through here, but it can also be accessed here.
