Fans of StarCraft II may have to wait a long time before the second game in the projected trilogy of sci-fi RTS games is released by developer Blizzard. The first game, Wings of Liberty, was released back in late July but according to a report from GameSpot, the second game, the Zerg-centric Heart of the Swarm, could be released almost two years after Wings of Liberty.

GameSpot reports that at the GDC Online event, Blizzard's Greg Canessa, the project director of Blizzard's Battle.net service, said they plan to make major updates to the service on the StarCraft II side of things "over the next 18 months between now and Heart of the Swarm". That may mean we could be waiting until April 2012 for the second game in the series to be released.
