In an interview with the Guardian, Assassin's Creed creative director Alexandre Amancio explains Ubisoft's mindset when creating Revelations and the caution his team is taking with Altair, Ezio, Desmond and their combined Body Mass Index.
"Well, Assassin's Creed has been going since 2007 -- the narrative is very rich and complex, so to avoid collapsing under the weight of our own mythology we needed to wrap up a few mysteries and set things up for what is to come. That's what this game is about: we're giving players some answers from Assassin's 2 and Brotherhood, we're completing the destiny of Altair, and we're tying it in to what's coming in 2012. And obviously, our over-arching storyline has to do with the end of the world in 2012 – we need to set up everything for the conclusion of that narrative. In this game, you'll get to understand why Ezio is so important and how his destiny his aligned to Altair's and to Desmond's."
It appears Amancio is focused on completing the first arc of the Assassin's Creed series with an emphasis on character development and clarifying the franchise's future, which can't be very vast considering he's counting on the world to end next year.
