John Cena is rapidly running out of opponents, and there are after all only so many up and coming talents he can bury before, during, and after WrestleMania. The fact that they've never had a match on the grandest stage of them all is surprising to say the least, but with the Streak seemingly no longer a factor, having a high stakes bout between the two of them next year could actually give everyone a reason to be excited over Cena again. There are a number of ways they could approach this one. Maybe Cena wants to have a match here with the Deadman to add yet another achievement to his already very long list of them, or better yet, The Undertaker could return as a heel determined to cement his legacy (possibly after losing to Bray Wyatt the year before) by taking out Cena. However you fantasy book this one, it feels like a match which has to happen at some point.
