Leipzig 08 interview with Gabe Newell on GameKings.tv talks with Gabe Newell at the Games Convention, asking the Valve boss about progress on Left 4 Dead, getting a hands-on demo of the game. Near the very end at about the 12:30 mark, Gabe admits to a slight delay for the multiplayer zombie game, which was previously expected on November 4 (story). Since setting that date they apparently realized it was tantalizingly close to the tenth anniversary of the November 19, 1998 release of the original Half-Life (story). Thus they have pushed back the release of Left 4 Dead to November 20/third week in November to coincide with the Half-Life anniversary. Thanks Voodoo Extreme.
