I don't think there is anybody who is going to beat The Undertaker at Wm. From what I gather The Undertaker will face John Cena at this years WM, because Taker needs somebody that will take care of him in the ring and be able to have a good match, The Rock will face Brock Lesnar. They are good friends in real life and I think The Rock will trust and be more comfortable in the ring with Brock Lesnar. The Rock is getting huge and seems to me like he doesn't want to look that small compared to Brock then they face off at WM. Cena will take care of Taker in the ring and will turn the streak 22 and 0. Rock will beat Lesnar for the first time setting up a possible 3rd match between the 2.
