At the opening of the Macworld Expo today, Blizzard announced that Warcraft III will be developed for the Mac. This makes the upcoming real-time strategy game the latest in a string of Mac OS games developed by the publisher, from Warcraft II to the recently shipped Diablo II. Blizzard has set Warcraft III for Macintosh on track to release at the end of 2001, while the PC version is expected by mid year.
