Yeah he should do, even though the two fought a while back Cena wasn't as big a star he is now. It has been over a decade in the making, no one has earned the right to face the phenom more then Cena on the grandest stage of them all; he has paid his dues and has been the man who put food on the table of WWE post 2005. It is fitting that Taker's final match should be against such a stand up individual which has never shied from doing what is best for the industry.
Taker doesn't owe us anything but as a fan we want to see him walk off into the sun set on a little bit of a high, much like what Shawn did for Flair at WM 24 I think Cena can be that guy for Taker. A lot of people are writing Taker of, oh he's too old, too inactive, too rusty and hasn't been himself; but they fail to realise that last year he had a severe hip injury and was asked to work Wrestlemania to put over Reigns (the guy they are positioning to replace Cena) ; Taker being the guy he has always been had no issue with it despite his health concerns and delayed surgery until after mania, he couldn't even prepare properly for the match but despite that had a decent outing in my eyes. He really is the phenom, can go from looking like he should be in an old people's home to someone that still got 5 years left in him

I have no doubt he's going to shut up a lot of people this year and I hope he gets the send off he deserves.
There have been rumours that Biker Taker could return but I doubt it because the phenom has never feuded with Cena unlike the American bad@ss.
