Ahead of this weekend’s virtual BlizzCon event, a Blizzard employee mistakenly posted PR information about World of Warcraft that discussed both Patch 9.1 and The Burning Crusade Classic. The leak was immediately posted to the MMOChampion forums. BlizzCon is being held virtually from February 19-20, 2021, due to the COVID-19 pandemic, and is free of charge.
Patch 9.1

While not much about Patch 9.1 has been set in stone yet, there will be a new 10-boss raid, the Sanctum of Domination, as well as a new eight-boss mega-dungeon, Tazavesh, the Veiled Market. In addition, there will also be a new zone, Korthia, the City of Secrets. The new PvP season will be released with 9.1 in addition to the next Mythic+ season.
There will also be additions to the covenants, such as upgrades to soulbinds and (possibly) new conduits. You can also fly in the Shadowlands in 9.1, although it is not clear what achievements will be needed to unlock flying. Flying will be similar to Legion with players only being able to fly in the four original Shadowlands zones of Revendreth, Maldraxxus, Bastion, and Ardenweald.

It is not yet known when 9.1 will release, but several reports have speculated a late May to early June release due to the amount of content involved.
The Burning Crusade Classic

While this was a matter of when and not if, The Burning Crusade Classic was also leaked. While all features of The Burning Crusade return (along with being free to play for World of Warcraft subscribers), there is also an option to advance characters straight to The Burning Crusade or opt to remain in WoW Classic. This is an interesting addition and may spark some debates in the community.
We’re looking forward to more information during BlizzCon Online this weekend. Stay tuned for more news about Blizzard games in the upcoming days!
