Not anytime soon. Look at Doom. There are still folks who make levels for the original games and actually play it online. I don't see Counter-Strike, which is far more advanced graphics and gameplay-wise dying for quite some time.
Activision will probably be publishing TF2 if Valve decides to release a boxed version. I doubt they'll actually show anything on TF2 at E3 though. They'll probably show Aftermath if anything at all.
Actually, Sony isn't at a disadvantage at all. They are the japanese equivilant of Microsoft. It's Nintendo who is going to have a really tough time. Especially since they are now dumping useless gimmicks into their game systems.
Yeah, I noticed that. Realistic water just doesn't fit well when the rest of the game looks pretty much the same as it did 7 years ago. I'd just wait for Black Mesa: Source. You have nothing to lose other than time since it's still in development.
I think Valve stated before they weren't using Source to it's greatest capability due to the hardware limitations of PCs at the time Half-Life 2 was developed.
I guess it's a good start. You might want to use an orange site template since it goes better with the Half-Life theme. And throw in the Lambda logo somewhere for good measure.
