1. The Undertaker
WrestleMania 32 was long expected to be The Undertaker's final match, with WWE likely putting him on last in his home state against John Cena. Those plans are now all changed. With Cena out injured and few other options available, Taker will instead be wrestling Shane McMahon. It is hardly the kind of grand name he would've wanted to bow out on, but there are no guarantees that The Undertaker will be back for WrestleMania 33. Indeed, Vince McMahon booked Taker to lose back at Mania 30 because he figured that was the last match. Being able to make it back for 31 and 32 is considered bonus time. Whether he can do that again for 33, and a potential match with John Cena, only time and circumstances will tell. For now, take nothing for granted, at 51 years old by the time of WrestleMania 32, it very easily could be The Undertaker's final contest.
