Just kidding.
But quoted from here: http://www.joystiq.com/2008/06/22/rumor-retail-chains-showing-december-3-release-date-for-starcra/
Many froth-mouthed fans of Blizzard's intergalactic real-time strategy masterpiece Starcraft have anxiously been awaiting word on when the next installment of the series would land in their anticipatory laps. Blizz has been characteristically tight-lipped about the title's launch window, though we were recently informed that an online SKU search for Starcraft II on Best Buy, Circuit City, and Gamestop's web sites reveal the same supposed release date of December 3, 2008. With no confirmation from Blizzard, it's far from official -- though we imagine this won't stop dedicated zerglings from dropping by the office tomorrow, and requesting off the last month of the year.
I trust joystick as source, I just don't think it's going to be released by then. And I just bought a new computer, so it better be spec'd for Starcraft II (or else I'm overclocking a fricking laptop - all bad.) Blizzard games have always been notoriously delayed and I still think it's going to come out early-mid 2009.
