-- The plan for Triple H is for him to turn heel at some point in his feud with Vince McMahon, possibly as soon as SummerSlam, but that has not been confirmed. It is said that the long-term plan is for Vince McMahon to be the face, and bring in a "conquering hero" to take out Triple H at WrestleMania 30.
-- WWE has posted a "web exclusive" SummerSlam preview on their official YouTube channel. The video description reads: "The Miz takes a stroll backstage and gets ready to host "The Biggest Party of the Summer" with other WWE Superstars such as Dolph Ziggler, Zack Ryder, and The Prime Time Players."
