-- The plan is for next week's Vince McMahon vs. Paul Heyman fight on RAW is likely going to be used as a setup for the Triple H vs. Brock Lesnar match at WrestleMania. Brock Lesnar is booked for the show and it's very likely Triple H will come out to "save" Vince McMahon from a beating at the hands of Lesnar. This will begin the build to their match at WrestleMania 29.
-- If The Undertaker has committed to working WrestleMania, the feeling is that Monday's RAW in Texas will be a perfect time for him to return. If he doesn't return live, they'll likely do some sort of tease with the lights going out or his music playing. With John Cena facing CM Punk on the show, one scenario being discussed is that the The Undertaker could cost CM Punk his match with John Cena, setting up their WrestleMania program.
