Although his picture looks like Morrissey is on safari in Cambodia, we're assured that it depicts Morrissey as the despicable Governor, who will be making his appearance in season 3.
In the accompanying TV Guide article, The Walking Dead co-creator Robert Kirkman promises that we'll get to see his character in full sinister form:
"The Governor in the show is definitely going to be The Governor in the comic . . . . I think that he's definitely going to be a character that people love to hate and are absolutely entertained by, but also somewhat terrified of. He's definitely going to be a very important character and a very nuanced character. We are not going to be watering him down."The Govenor first appeared in issue #27 of The Walking Dead
