After much controversy, The Walking Dead once again has a Showrunner. Supervising Producer Scott M. Gimple has been promoted from within and will now take on the big time role of running the show. He joined the series at the beginning of Season 2 and has been working his way up ever since. (You can either be happy about or ignore the fact that he wrote Ghost Rider: Spirit of Vengeance.). At the very least we know he was part of the show during season 3 - when it got great again - so hopefully he can maintain that. He also is said to be a big fan of the source material.
Gimple will take over for Season 4 of The Walking Dead as Glenn Mazarra will see it through the end of season 3. This is the third showrunner in the show's four season history.
We have less than a month until the show is back on and it's nice to know that it will be left in someone's hands that can help carry through the transition. On the other hand, that sounds like it will be an awkward place to work for a few months.
