#4 The Undertaker will retire

Another WrestleMania, another Undertaker retirement prediction. It feels as though The deadman has been rumoured to retire at every WrestleMania since his shock defeat at the hands of Brock Lesnar at WrestleMania 30 but surely, this has to be the year.
It looked as though Taker had hung up his boots following his defeat to Roman Reigns at WrestleMania 33, but the WWE managed to convince the former World Heavyweight champion to lace up his boots once again at this year's event, and he has made several televised appearance since then as well.
Cody Rhodes' uncle is a WWE Hall of Famer. More details HERE.
Taker's current program with Triple H and Shawn Michaels does appear to be preparing the deadman for one last ride though, and seeing him go out against one of his all-time greatest rivals would probably be a more popular way to call an end to one of hate of the most iconic characters in wrestling history.
