First, he revealed that Michonne, the caped crusader who made a cameo appearance in tonight's episode, will be played in season three by Danai Gurira. The American actress was in the HBO series Treme, which I've heard wonderful things about. Michonne is one of my favorite characters from the show, so I have pretty high hopes for Gurira's performance. This announcement runs somewhat in contrast to earlier spoilers which suggested that True Blood's Rutina Wesley would be playing the samurai heroine. Regardless of who plays her, I'm just glad she's decided to show up. Read further about the announcement here.
Kirkman also took his time on Talking Dead to hint at the reappearance of at least one character from seasons past. When asked if we would see Merle Dixon, Morgan or Duane in season three, he responded that he could "100% guarantee seeing 33% of those people in season three", suggesting that one of those characters is already written in to the season. I think smart money is on Merle, but Morgan and Duane do come back up in the comics although not until much later. Seems like Michael Rooker may have spoiled Kirkman's spoiler about 24 hours early though, when he announced he would appear in season three during a convention panel. Check it out here.
Can't wait until next season? I'll keep you posted with news and updates as I come across them.
