Why go back to the Crusades when we've already explored the Third Crusade and there's still so much of history yet to explore?

And with Assassin's Creed IV: Black Flag picking the well-explored Golden Age of Piracy setting so Ubisoft can show how the setting can be done accurately, I'd say the other settings like Ancient Egypt and Feudal Japan are possible settings once more.
