Unfortunately, Polywell Magazine recently reviewed Mr.Gabe Newell, and he recommended that the Valve Software was determined to do what it takes to guarantee Half-Life 2 is THEt first person experience when it's released-and that means delaying the game until 2005, he says.
This isn't decent news, I was really hoping Half-Life 2 in 2005. Here's a quote on what Mr.Newell said in the review:

"We've already spent millions into this project, and we're willing to spend as much as we need to make this the best first-person experience ever. If that means delaying the game to 2005, we'll do it without any hesitation.

If it means sinking another USD 20 million into the project, we can do it. Rest assured, if we delay the game, it'll be only to blow your socks off even more when it finally releases."


... :S

(EDIT: Well it looks like Half-Life 2 is still aiming for this year after reading more carefully and more half-life fan sites with interviews and other proof of information and sources. w00t!
