The topic of a full Counter-Strike sequel has been cautiously broached by Valve during a series of interviews with GameTrailers TV.

"We will never abandon Counter-Strike," asserted Valve director of marketing Doug Lombardi, who went on to explain why the game hasn't received a major update since the release of Counter-Strike Source in 2004.

"It's a little bit unfair to compare Counter-Strike, I think, to your classic game that's gonna have these sequels. It looks a little bit more like an MMO where it's constantly [being updated]."

Of course, even the most successful MMOs get sequels eventually, and it appears that Valve is at least tentatively working out the details of a Counter-Strike refresh.

We're not ready to announce CS2 yet.. All we can say is, CS2 is being worked on at the same time CS 1.3 is being worked on..

No word on if CS2 will be stand alone, working with Half-Life2, or TeamFortress2. There is a mention of a release date there as well, but release dates this far off are about as valuable as chihuahua farts in a plastic bag.
