Much ado about nothing. I believe Stern's orignal theory, from when the Letterman brouhaha first broke: Letterman leaked the story as a negotiating ploy. He's not going anywhere. Worked like a charm.
Maybe, but Stern wants on. I'd bet on it. The only question, IMHO, is where he goes on the air.
I heard the interview with Drudge - at least the tail end of it. Stern might be a good fit on Fox opposite Letterman and Leno. I'd watch it in a heartbeat.
