WrestleMania week is typically the biggest week in wrestling. It's not uncommon for other wrestling companies to hold events in the same area as WWE during WrestleMania week, but it doesn't look like ROH will be part of the festivities this year.
WrestleZone is reporting that sources in the Las Vegas area have claimed that ROH Supercard Of Honor 2025 was originally set to take place in Vegas during WrestleMania weekend. It was noted that AEW had a venue picked out, but those plans are now off, and the venue situation is up in the air.
All Elite Wrestling had reportedly been working with a venue near Fremont Street that had been picked for the ROH event. The plans were nixed and the reason for the change is unknown.
As of right now the belief is that Supercard of Honor could still happen in a different location on a different date, but as of right now it won't be happening in Las Vegas in April.
It's worth noting that Fightful Select recently reported that as of last year there was major discussion within AEW about moving the Double or Nothing pay-per-view away from Las Vegas. In years prior the event has emanated from Las Vegas in May, but WrestleMania taking place in Las Vegas one month before is said to be a deciding factor.
According to the report AEW is unlikely to release their entire year of pay-per-view dates ahead of time like they did last year. WWE holding a competing show in Orlando last month during AEW's Worlds End pay-per-view was cited as the reason for the change.
