If they plan to follow the comics' storyline a bit, he will certainly be dead by this season, maybe by head-smashed-in-by-biker's-foot way.
I'm not watching the show anymore, it's become too boring and tedious with the occasional zombie and death every few eps.
The show is geared towards the new generation of American audiences the ones that find a George Romero type of Zombie stories lacking in character development,as just George Romero said "Walking Dead" is a soap opera with an occasional zombie in it.
Its pointing at Glenn's date towards the end of the season,spoilers from fans in Atlanta reporting about walls that resemble the Alexandria compound. I'm sure that either Bob,Shasha or Tyresse will die too this season and Carl will lose an eye.
