AMC announced through TCA press tour on Friday, January 7 that "" season 2 will be longer than the first one. The network still has no premiere date but it confirms that the new season will consist of 13 episodes which is more than a double of the first.
Regarding what to expect, AMC President Charlie Collier said, "Frank Darabont, Gale Ann Hurd, Robert Kikman, Dave Alpert, Greg Nicotero, and the rest of the crew [are] figuring out where to take the zombie apocalypse from here. We lost a few along the way as sometimes happens in 'The Walking Dead,' but a few surprises in there as well. Shane, Jon Bernthal, lives for season two so we're going to keep it fresh and it'll be back and better than ever."
