1. John Cena Vs The Undertaker
There is at least a decent chance Undertaker vs Cena happens at Wrestlemania 30, and if not then a very good chance it will go down at Mania 31 or Mania 32. Simply put, this is the biggest match that WWE has in its locker. They have clashed early in Cena's career, but have had no significant contest in a very long time now. When they finally meet in a big match setting it will make for a formidable event. The place will be have to be Wrestlemania. Cena vs the streak is the last remaining challenge that Undertaker needs to overcome, the final and biggest star he will have faced at a Mania. As a story, as a box office draw, as a match it will be explosive. I fully expect it would be one of Cena's best matches ever, right up there with his efforts against Edge, Punk and Michaels. Given Cena's position as a superman, it would raise serious questions of the streak ending. That is a compelling sell right there. A dream match that I really hope we get to see on the stage of drama it deserves.
