This game have been producted SINCE Assassins Creed 2. Brotherhood and Revelations were likely a delay for the game, to give more time for Ubisoft to product it and to keep the fans happy.

3 years of production, my friend if, i am not wrong, AC 2 was in production for 2 years.

Most( if not all ) of the good new features are back, like the Assassins system and some form of the hookblade.Also they took away the bad things, like Den Defense.
