He'll sue, get all the money owed for season 9, plus continue to get the royalties from all the reruns through syndication.
He's got his new book, Apocolypse Me: The Jaws of Life

and he'll get back into movie roles.
He's far from bat shit crazy imo. He's playing to the camera on Ustream and is actually being honest. Now if he was jumping on a couch with Oprah and was a scientologist, then he is bat shit crazy.
