Get your picket signs ready. Mtv plans on replacing the entire cast of ‘Jersey Shore.’ What will Snooki do now? No reason was given for the decision, but my guess is it’s more financial than creative. Mtv probably attributes the show’s success to the concept rather than the specific cast members, and they think they can strike gold twice with less overhead. They know that the current cast will request a major salary increase at the end of Season 2, and so they figure they’ll sack them and get some cheaper nobodys. Big mistake guys.
