^ Yeah, I dont think WWE would want the Rock to be put in the highlight positon at SS because of his Wrestlemania match with Cena, What WWE want is people to get back in with the Rock and get excited when he's around, so when WM comes his match with Cena will blow the ratings. Thats why they have brought him back after months.
In some ways its a good thing if they bring him to SS because atm its all about CM Punk, HHH and Kevin Nash, Hopefully this could keep that storyline going, but at the same time get the Rocks attention so it doesnt get boring.
