Its been stated that there are three possible WrestleMania 29 opponents for The Undertaker – The Rock, Brock Lesnar and John Cena.
Additionally, its been said the decision as to who The Undertaker
works with is being left up to him. While WrestleMania 29 is still nine
months away, it seems whichever two names are left out of the fold after
a decision is made with The Undertaker, those two guys would likely
work with each other at WrestleMania.
For example, if The Undertaker decides he wants to work with John Cena, it would likely mean The Rock takes on Brock Lesnar.
Personally Id like to see ...
Undertaker Vs John Cena
Lesner Vs The Rock
Undertaker Vs Lesner would also be good but that would mean a return fight with Rock and Cena and I dont really want to see that again even though there fight was good at WM28.
