I bet you haven't read that anywhere else yet. Ahem. Anyway. Shacknews points out that Valve is only as reliable as about 95 percent of the other companies in the software industry. Which means that Half-Life 2 won't be available later this month. While I'm not terribly surprised by this statement, I have to say though that the well planned announcement earlier this year in combination with Gabe "you can quote me on that" Newell constantly confirming the 9/30 release date somehow didn't make it look like an absurd idea. Half-Life 2 is now set for a "holiday release." However, it's not like there isn't a number of other excellent PC titles oncoming this Fall and maybe this is your chance to check out some games that would have been ignored otherwise.
Update: According to this GamersHell tidbit the Shacknews information above is fake and Half-Life 2 went gold. The CDs are supposedly in the production as we speak. We'll keep you updated on which of those two is the 'real fake'.
