Why I believe ACIII should NOT be mainly modern in time setting.

First, let me state that I have not yet played Brotherhood, so I have no clue what happens there storywise. 
 
There are a lot of people out there that want ACIII to be entirely Desmond outside of the Animus, or possibly papa-Desmond. I think that any time period new than the 1860s would break the Assassin's Creed gameplay.  
 
Why? Well, so far the AC games have been set in time periods where projectile weaponry wasn't much more advanced than bows/arrows and single shot guns. In modern times, guns can hold lots of bullets, and really the only way to fight back against guys with automatic weapons is to also use automatic weapons, which would essentially turn AC into a third person shooter, and I know that's not where I want the series to go. 
 
But I have a feeling that the developers didn't think of that. Why? Remember when you fought against Abstergo guards in ACII? I do, and I specifically remember that instead of being armed with something normal (guns), they had plastic rods. Really? They really had to include Desmond combat so badly that they equipped guards that work for an evil corporation (and/or Templars) with plastic rods? That's just dumb.  
 
Also, part of the reason why the traversal is fun is because of how olde-ass cities were back then. Lots of low lying buildings close to each other. Modern cities aren't like that.  
 
I'd also like to point out that ever since the first game, I haven't liked the story stuff outside of the Animus. It just seems like a way to explain the switch of main character from one game to the next, and how to explain things like dying and coming back to life. And I don't really see it getting much better in future games.  
 
So Ubisoft, please, don't make most of ACIII be outside Animus. I don't really care when the in-Animus takes place, just please set it in a time period where guns aren't the primary weapon.
