WWE Championship match could be a triple threat match as WWE Chairman Vince McMahon and Stephanie McMahon-LeVesque told WWE writers to make The Rock's involvement in Wrestlemania 27 not only as an host but also as active participation in a match.
Vince McMahon want The Rock's involvement as a major in WWE and much better then Bret Hart's return. If all this is true, then we may see John Cena vs. The Rock at WWE's PPV Summer Slam.
