Blizzard announced today that the highly anticipated Starcraft 2 is to be released as a trilogy. All three games will have the same multiplayer and skirmish modes with all the three factions, but each will have a different campaign based on one of the aforementioned factions. The reasons for doing so are apparently to maintain the quality of the game, and to avoid delaying the release. The price of each one is yet to be announced, but it would be undeniably cheeky to release each one as a full priced game. 2009 is the only vague release date known.
