From EW's Michael Ausiello:
Sources confirm to me exclusively that creator Eric Kripke will be stepping down as the CW drama's day-to-day showrunner next season. Executive producer Sera Gamble, who has been with the show since season 1 and is awesome, is poised to succeed him.
But, and this is a big but, Kripke will remain actively involved in the show - and not just in name only. Although CW and Warner Bros. reps declined to comment, a Supernatural insider assures me that Kripke and his current co-showrunner, Robert Singer, will continue to function as hands-on executive producers.
"Eric and Bob will be working very closely with Sera," says the source. "They are not abandoning the show."
Kripke has long said that he envisioned Supernatural as a five-season show. But in an interview last August, he clarified that stance. "I'm looking at this season as the [last] chapter in this particular story," he told me. "That doesn't mean there can't be a new story. Buffy did it. The X-Files did it. You close a chapter on a big mythology storyline and then you begin a new one." Asked whether he would be involved in a possible sixth season, Kripke hedged, "I don't know. I'm going to cross that bridge when I get to it."
Kripke is said to be finalizing a new deal with Warner Bros. that will feature a big development component. In other words, his diminished role on Supernatural will free him up to create another awesome show.
It's all about the silver lining, kids! C'mon, work with me here!
Okay, fine. I'm sure all you're seeing is the dark cloud that is Kripke's big (euphemism alert!) career transition, so use the comments section to work through your anger issues.
