Hi all, AMC has published information about season four production, here it is:

Scott Gimple, as we knew, is the new showrunner; Greg Nicotero and Tom Luse were elevated to executive producers; Kirkman says "I'm thrilled to begin work on a brand new season of The Walking Dead with Scott at the helm, and I truly believe we could be embarking on what will be the best season of this show yet". 

I'm really excited about this after reading that. Opinions?
