Blizzcon announcement: Starcraft II will be episodic

While an anonymous poster and Zarkil were the first to guess that Mike Morhaime only announced a new Diablo III class, the Wizard (how original), the real news came somewhat later at the Blizzcon 2008: Starcraft II will not be one game, but three. You can buy the main campaign for the three races as separate packages. Is that a cheap money-tripling scheme from Blizzard or a useful service? Discuss!
