According to PWInsider (beware of pop ups and other tomfoolery if you click this link) Shaq and the WWE are not done. There are rumors floating of a Big Show appearance on Shaq's new reality show Shaq Vs.
The Big Show would be one of many star athletes Shaq plans to battle in their sport of choice. Already signed up for the show are Michael Phelps, Albert Pujols, Lance Armstrong, and Ben Roethlisberger. O'neal was the one guest GM that was an unqualified success, boosting the rating and making the show more interesting at the same time. They'd love to have him back on RAW where he is a natural comedic talent and a great foil for their big men.
