World of Warcraft Classic Launching The Burning Crusade Expansion Later This Year
Blizzard announced today at Blizzcon that The Burning Crusade will be coming to World of Warcraft Classic later this year in 2021. This shouldn't come as a surprise, as when WoW Classic was first announced most people figured The Burning Crusade and subsequent expansions will soon follow up.
Burning Crusade returns.

No word on exactly when The Burning Crusade comes to World of Warcraft Classic, but given that Classic launched in August, 2019 and The Burning Crusade is coming out later in 2021, players can probably expect The Wrath of the Lich King sometime in 2023.
