Leave it to Valve to lower requirements before a release hehe.
Anyway, it was never really too high of requirements anyway...if you can run most modern games on decent settings, you can run L4D on good settings.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
