Nah, it's called TripleMania because it's Triple A's version of WrestleMania. They tried out doing three shows in the mid 90s, but for most of its existence, they just did one show. In 2019 (right before the pandemic), and 2021 (when the pandemic slowed down a bit) they added TripleMania Regia to the schedule in the winter, sort've like an end of year WrestleMania, but for the Northern Mexico audience.
They're really breaking it up into three shows to hit Monterrey and Tijuana, since there is absolutely no guarantee that they can get people to make the trip down from Northern Mexico to Mexico City for one show.
