4: The Rock Returns

Following Ronda Rousey’s arrival at the Royal Rumble, rumours instantly surfaced online that she would be teaming with The Rock at Wrestlemania to take on the team of Stephanie McMahon and Triple H. Those rumours have died recently, with many sites reporting that The Rock, unsurprisingly, is otherwise occupied.

The prospect of a Rock and Rousey team up, though, would mean big money for the WWE and from a storyline perspective, it would make a lot of sense as a continuation of their in-ring segment from Wrestlemania 31.

This is highly unlikely, but if it did happen, you could guarantee The Rock would get the biggest pop in the event’s history.
