So if Megyn is in at 9, what happens to Sean Hannity?

In a developing story, Drudge reported on Thursday that Megyn Kelly at Fox News Channel, usually an afternoon anchor who is currently on maternity leave, will return to the network at the 9:00 p.m. slot. Since that is where Sean Hannity's show is currently aired, the question becomes what happens to Hannity? And what other shakeups are in store for Fox?
