George Wang, from Blizzard Public Relations, told CNN of a new game announcement to be made at BlizzCon:

Blizzard expects up to 6,500 guests at BlizzCon, thanks in large part to the staggering worldwide success of “World of Warcraft”. Over 3.5 million people pay $12.99-$14.99 per month to play the game. In addition to the opportunity to chat with the makers of the game and attend a concert, attendees will be the first to see what’s next for Blizzard.

“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”.)
