– Shawn Michaels is scheduled to be the special referee for the Undertaker vs. Triple H match at WrestleMania. Since Triple H and Shawn Michaels have both failed twice at ending the streak, it lends something to the idea that they could work together to screw Undertaker.
Triple H might put his career on the line against the streak. The Undertaker vs. Triple H match will be promoted as the #2 match on the card, behind Cena vs. Rock.
– John Cena recently mentioned that his match vs. The Rock at WrestleMania would be even bigger if it was for the WWE championship. At the time he made the comments, WWE was strongly considered putting the title on Cena heading into WrestleMania.
The WWE title being on the line would make the match seem bigger and elevate the status of the WWE title. Additionally, if the title wasn’t on the line in this match, it doesn’t look great that the WWE title match would be billed as the #3 match on the show. That said, WWE is firmly behind Punk as champion and the Rock vs. Cena is already guaranteed to be a huge draw without the belt on the line.
