As we all know, Rick Grimes won't live as long as he has done in the comics. I believe this simply because I think Andrew Lincoln will move onto another project as most actors do, they don't like to be tied to one show.

So what I want to know is; When do you think Rick will be killed off? My guess is in season 5/6 as Carl will be old enough to take charge, or Michonne for that matter.
