Glenn Beck leaving Fox. Who will replace him?

http://nma.tv/ What will Fox News do with Glenn Beck's time slot once he leaves the network? Fox should consider alternative programming possibilities rather than shoehorn another personality into the vacant spot, like another network is doing with their show. Perhaps Fox could commission its own version of the 'Bad Girls Club,' starring its feisty female newsers. Fox loves the Palin family. How about 'Bristol Palin's Extreme Face-over?' Or they could revive 'In Search Of,' where Donald Trump looks for a different historical figure's birth certificate each week. But maybe Greg Gutfeld is the real answer. It would make sense to move 'Red Eye' to the 5 PM slot, when people are actually awake.
