I was in Best Buy today upgrading my ram and mentioned to one of the employees that I was gearing up for Half-Life 2. He then tells me "You know you can buy it today. We have it in stock". I was like, "Uh I thought it wasnt coming out till Tuesday?" And he then tells me that Valve canceled the street date which left it open for retailers to sell the game. So in other words, go get your copy! Call ahead first. This was at the Best Buy in Duncanville, Tx.
