For Wrestlemania 29, WWE decided that they quite liked the money to be made from a match between The Rock and John Cena, and so decided to ignore their promise of 'once in a lifetime' from the previous year, and book a rematch between the two, this time for the WWE Title. Rematches were the name of the game for the show, as in a return bout from their clash at SummerSlam 2012, Triple H would battle Brock Lesnar in a no-disqualification match, where Triple H would be forced to retire if he lost. In addition, CM Punk would battle The Undertaker, The Shield would make their Wrestlemania debut, and Chris Jericho would take on Fandango.
