From the PlanetXbox360.com feature top 10 list:
"The Assassin's Creed franchise has spanned some pretty interesting and picturesque locales and time periods. Now that Ubisoft is officially done with the stories of Ezio and Altair, there's no reason to doubt that the third proper installment in the franchise will take Desmond and/or another ancestor to a completely new setting. The latest game, Assassin’s Creed: Revelations, ties up the entire storyline by letting you control both Ezio and Altair, the most recent AC game released just days ago; the entire Assassin's Creed franchise is one of our favorite series across the entire lifecycle of the Xbox 360, so to say we are excited about where Ubisoft is heading next would be a massive understatement. So without further ado, here are our ten favorite settings for the next Assassin's Creed video game."
