Staysafe TV explains that Blizzard is already making plans the beta for the Burning from lidakun's blog

In extra detail, Staysafe TV explains that Blizzard is already making plans the beta for Buy WOW Classic Items  the Burning Crusade update. This beta will tentatively arrive sometime in mid-February. 

A pre-patch will then follow on April 13, observed by the expansion's full launch. This fits the familiar pattern for World of Warcraft enlargement launches, however would not have any organization proof to guide it outside of Staysafe TV's claimed nameless source having showed it. As such, it's worth remaining skeptical.

The one issue of this situation that does sound sensible is how a great deal it coincides with Blizzard's existing plans for BlizzCon. Blizzard delayed and is retaining BlizzCon online this yr. It will formally begin on February 19. Based on Staysafe's leak, which means that the Burning Crusade beta should start straight away after or round BlizzCon. As such, it'd make for  mmobc.com a fitting assertion throughout the show.
