Because Valve's breaking out the big guns. Counter-Strike: Global Offensive was announced today to be released in 2012 (adjusted for Valve-time of course). New maps, new characters, new weapons, and de_dust.
That's assuming something announced comes out in 4-5 years time.
We're already past that for HL2: Ep 3.

It's sad how true that'll likely become.

I was thinking more like War Inc.
It is free to play, but you can spend coins (in game currency) to "rent" weapon by the days (1,3 or 7) or earn the permanently via Cash Dollar (I think they call it Gold Coins or something which cost real money to buy)
