I really see it playing out with multiple characters.
Episode 1 would be you controlling Kenny as he escorts Clem out of Savannah. 2 would put you in Clem's shoes as you wander those fields, trying to track down Omid and Christa. And so on and so on.
It'd be pretty neat if they could pull a multi character thing off--your choices would effect their personality and everything.
It's a long shot, but man... that'd be so cool.
