Evil Avatar has the word that even Best Buy is selling Half-Life 2 boxes
at this point. If you're planning on picking this one up it should be available pretty much anywhere. Voodoo Extreme has news from Steam that in no uncertain terms
are the delays in opening the game to customers their fault. From the article: "This is not Valve's choice. Vivendi is insisting that the game has not yet been released, and has threatened that Valve would be in violation of its contract if we activate the Half-Life 2 Steam authentication servers at this time."
