The Burning Crusade to be announced at BlizzCon

This was brougth to my attention recently, and according to Blizzard's PR guy George Wang BlizzCon's going to have an announcement of some sort regarding to World of Warcraft.

"We're going to be showing off a new product we haven't announced yet," said Wang. (And for those thinking it's the long-rumored unveiling of "Diablo 3" or "Starcraft 2," get ready for a letdown. Wang said the announcement will be linked to "World of Warcraft".)

Link.

We all know what it is.
