Expect entire cities to stop working on May 15th. For that will be the day Blizzard Entertainment, in their lifelong battle against productivity, will unleash Diablo III upon the masses. The official website is officially open for pre-orders, or World of Warcraft players can net a free copy by signing up for a WoW Annual Pass. Diablo III will continue several community features begun under Starcraft II: Wings of Liberty, including the RealID cross-game chat and friend system for Battle.net.
