At BlizzCon today, the game company announced that it will be giving away Diablo 3 to its subscribers who decide to sign up for the World of Warcraft annual pass. That means signing up for a 12-month subscription commitment to World of Warcraft. In addition to getting Diablo 3 for free, annual pass subscribers will also get a Tyrael’s Charger WoW Flying Mount for all current and future characters (to be made available with patch 4.3), and a guaranteed spot in the beta test for the next WoW expansion set.
