If you do not already have a subscription to World of Warcraft, it might be a while until you are able to get one. To say the least, the "test run" they mentioned in their January 10th press release has not been going so well.
"We haven?t requested that any retailers pull the games they already have off their shelves," Gil Shif, public relations representative, said. "We're just being careful not to release additional copies to be sold until we feel the game servers can support additional players."
Blizzard declined to comment on how long it would be until more copies of World of Warcraft would be shipped to retail stores.
Some rumors had been circulating that Blizzard had pulled copies of World of Warcraft currently on sale from the shelves of video game retailers across the country, specifically Best Buy, to limit subscription growth. As for now, large retail chains such as Best Buy and Walmart currently do not have any copies of the game available. Even Blizzard's official on-line store currently says that they are out of stock.
