The World of Warcraft development team has confirmed that BlizzCon attendees will be able to go hands-on with a playable sneak peek of the upcoming World of Warcraft expansion. For those who won't be able to attend BlizzCon, gaming magazines hitting newsstands in different regions of the world around the time of the event will feature in-depth previews on the new content we have in store.
