The Walking Dead (TV) - Someone Is Going To Die In S3

TVLine has an interview with Michael Ausiello, where he's asked the following question:

Question: Will a series regular die on The Walking Dead by the end of first half of Season 3? 

Ausiello: I can confirm that a series regular will become zombie kibble during Season 3, but whether that death takes place in the first half or second half I can’t say.

So, no word on who or when, but we do know that a "series regular" is going to die during the third season, which starts on 14 October. Who do YOU think is going to take a dirt nap (or become a roamer)?
