*blinks* I don't think you are quite all that sober at the momemt.
Valve has mostly turned from a developer to a publisher, anybody should have seen the writing on the wall since they had issues with the HL2 chapter issues and with Steam taking over as it has back in the day.
As I see it, as long as TF2 keeps the money flowing in, the urge to finish HL2:C3 won't happen any time soon.

You are most probably right, they are far too busy working on Hats for people to buy in Tf2 to worry about finishing the story of a much loved game series.
Except that they actually are working on Half-Life 3, and have been since the Orange Box released.

And just in case you don't pick up on the sarcasm and innuendo in the article, Newell means "Half-Life 3".
Also, I wouldn't get your hopes up for Episode 3. There's virtually no chance the next Half-Life game will bare that moniker. It'll likely just be Half-Life 3.
