Confirming an earlier leak on its website, the expansion will be released on September 26, 2022.
It will launch globally at 3pm PT (11pm BST) and will be available on all World of Warcraft: Burning Crusade Classic realms.

Announced in April, the recreation of the game’s second expansion will free be for any player with an active World of Warcraft subscription.
“The epic moments in Wrath of the Lich King Classic feature vast icy environments, unique dungeons and raids, and a gripping conclusion to the story of Prince Arthas,” said World of Warcraft executive producer Holly Longdale.
“All of this and more made it a favorite of many of our players and us at Blizzard as well. We’re looking forward to providing an authentic experience for returning veterans and an awesome adventure for newcomers exploring Azeroth for the first time.”
World of Warcraft’s next new expansion, Dragonflight, will also be released later this year.
Blizzard launched the Dragonflight alpha test earlier this month. Phase one of the alpha focuses on several features of the expansion including one of its four new zones, the frosty peaks of Azure Span.
It also introduces dragon riding, an all-new skill-based method of aerial travel which lets players fly around on a customisable drake.
And it includes World of Warcraft’s first ever combination race and class, Dracthyr Evokers. Players can create both humanoid and draconic forms, pick between the Alliance and Horde, and choose to be a healer or ranged damage-dealer.
Players who want to participate in the alpha can opt-in for a chance to become a tester. Blizzard has said it will be sending out invitations regularly throughout the test.
