Hulk Hogan has yet to put pen to paper and sign a new WWE contract. However, Vince McMahon apparently believes in Hogan's word enough to invest serious television time into him.
While McMahon is under the impression that he has a verbal committment with Hogan, and a merchandise committment, which is legally binding anyway, Hogan can still walk out and go home if asked to put over someone he isn't interested in jobbing to. We all saw this scenerio last year when Hogan was asked to put over Lesnar a second time at the Survivor Series pay-per view.
