#3 Conor McGregor shows up in some capacity
Conor McGregor recently announced his 'retirement' from the UFC. Even though I think it's not an actual retirement, I won't be surprised if he shows up at WrestleMania in some capacity in the same way Ronda Rousey did half a decade ago.
Although unlikely, I could see WWE really going to secure an appearance from McGregor if there's an opportunity.

#2 John Cena is Kurt Angle's final opponent
As it stands now, Kurt Angle will be facing Baron Corbin at WrestleMania in the last match of his career. The match was met by a negative reaction from most WWE fans and even Angle's wife Tweeted about it being a disappointment before later deleting her Tweet.
However, I still think that Corbin vs Angle is just a placeholder. I still pretty sure it will be John Cena who will be Angle's surprise opponent at WrestleMania.
