There are strong rumors out there that Survivor host Jeff Probst could be in his swan song with the show as his contract is up after these next two installments in Nicaragua. Probst has made no secret about his desire to break into other media ventures and was mentioned prominently as a potential replacement for retiring Larry King and his CNN show. Survivor itself is signed by CBS only through S22 but the next location for a possible 23 and 24 editions have already been set for the Phillipines.
My View: I love Probst just as much as anyone as he truly has made this show his own. No doubt ratings could take a big hit when he leaves (a la Simon Cowell leaving American Idol and their expected ratings drop) but at this point its only rumors. I still think in the end Probst wont leave and I have been told that Survivor will likely be renewed for 23 and 24 in the few months or so.
