World of Warcraft may not be quite as popular as it once was, but it's still going strong and tonight we expect to see the first signs of the next expansion. If you take a look at the BlizzCon schedule you might note that "World of Warcraft: What's Next" fills the first slot following the opening ceremony on the main stage.
A recent trademark and subsequent rumours have it down as "Warlords of Draenor" - supposedly featuring a time travelling theme and Grom Hellscream as the main villain.
