According to sources, there is a growing feeling that this WrestleMania will actually end up being Undertaker’s last one and is primarily the main reason that WWE has quickly set up a Taker vs. Roman Reigns match at the show. Vince McMahon reportedly wants to have Reigns and Taker face off at a major PPV before that window of opportunity runs out and it is a very likely explanation why the originally planned Underaker/John Cena match was called off.
The working plan right now still appears to be have Brock Lesnar defeat Goldberg at WrestleMania 33 for the Universal Title and then to have Roman Reigns defeat Lesnar sometime over the next few months, possibly at SummerSlam.
The chances of Naomi being cleared in time for WrestleMania are said to be “50-50 at best” according to backstage reports. WWE is said to be going with a multi-woman match for the title as it would allow them to include Naomi in the match should she be able to return in time.
