A report by Dave Meltzer in the new issue of the Wrestling Observer Newsletter explains why the direction for the top matches at WrestleMania 37 remains unclear:
The reason there has been no television direction for the main matches at Mania and you don’t hear anything about them is because there isn’t any. The only thing we know is the top Raw championship matches are not locked in. On SmackDown, Reigns has two different opponents that are being considered so Bryan is not a lock and at least as of this past week, Nakamura was not one of the two under consideration as of last week, even after the gauntlet. Then again, if you followed the Kingston deal a few years ago if they sense people want something, it’s possible to change and in fact, plans change daily anyway. But with no crowds, while plans will change, the change to Nakamura in that spot is less likely but nothing is impossible.
Meltzer also reports that as of earlier this week, WWE is planning for an attendance of 30,000 on each night of WrestleMania 37:
Inside WWE, the plan looks to be to put 30,000 people in the building both nights. If the Super Bowl puts in more, they’ll likely put in more. But that was the legit goal as of early in the week. What they’ll announce is anyone’s guess. The shows will likely be four-and-a-half hours with the first match going in the ring at 5:30 p.m. and the targeted ending at 10 p.m. The Tokyo Dome did two five hour shows. The second day was tough, as it was last year, and as it was to a degree with WrestleMania last year, but in the long run it was the best for all concerns. Right now it doesn’t look like that will be the plan going forward, but two shows at four-and-a-half hours leads to better matches and longer matches and higher quality shows than one at seven. Plus there is more money to be made. In the past you could argue it would break tradition or it just wouldn’t work, but New Japan has proven two years running that it does.
WWE announced last weekend that WrestleMania 37 will be held on Saturday, April 10 and Sunday, April 11 at Raymond James Stadium in Tampa, Florida. It was also revealed that WrestleMania 38 is scheduled for April 3, 2022 at AT&T Stadium in Arlington, Texas and WrestleMania 39 is set for April 2, 2023 in Inglewood, California at SoFi Stadium.
