Want Diablo 3 for free when it launches? Just sign up for Blizzard's newly announced World of Warcraft "Annual Pass".

The pass is a 12-month subscription to World of Warcraft that can be billed monthly or all at once. "This is the full digital version of the game -- not a trial or limited edition," said Blizzard CEO Mike Morhaime. The WoW annual pass also gives you guaranteed access into next WoW expansion beta and an exclusive in-game mount called Tyriel's Charger based off Diablo III.

The annual pass is available now.
