The Undertaker vs. Roman Reigns match will be the likely main event and final match at WrestleMania, according to Dave Meltzer on today’s Wrestling Observer Radio. There were earlier reports that Goldberg vs. Brock Lesnar would be the final match, but WWE seems to have decided on Reigns/Taker closing the show instead. Goldberg vs. Reigns is still the “second main event” but that doesn’t necessarily mean that it’ll be the second to last match.
Meltzer claims that Undertaker vs. Reigns “is the very probable if not for sure main event” but things could obviously still change since WWE makes last minute changes very often.
It seems like an interesting decision by WWE, since Reigns is expected to win and will probably receive heavy boos, leaving fans “upset” at the end of the show. WWE could also possibly try to do something where fans are supposed to respect Reigns for a “hard-fought win” and Undertaker raises his hand respectfully or something. They could also be banking on fans realizing that “none of this matters” and it is meaningless to be so upset at Roman Reigns beating the Undertaker.
