Jockyitch is posting the following informaton from his twitter during the Bashandslash live webcast:
GSPs will not like the news today. MW2 for pc will not have dedicated servers.
The CoD Community will be completely different post MW2. Things have changed a great deal. We will need to embrace change in the future.
MW2 gets VAC NOT PunkBuster!!
Sorry....iwnet replaces PC dedi servers....agn: no dedi servers for MW2 --> from Fourzerotwo on bash right now.
I am listening to the webcast now and will post more information up as it comes available. The above statements have been said by Robert Bowling (402) being interviewed in this webcast.

UPDATE
So after listening to the webcast these are some of the points brought up by the hosts of the webcast about these changes:
IW has control of the game.
IWnet servers will host multiplayer.
DLC will be a charged item for PC.
No dedicated servers.
Semi-capable password servers.
Semi-capable ad-hoc servers.
Competitive play is dead.
MW2 mods would not be possible.
Full integration into Steam.
PC has been turned into console.
Will Treyarch pick up the dedicated server side?
What does this mean to everyone? What will Treyarch do? Do you think CoD for PC is dead? What does this mean for CoDTV as all versions still have it?
The webcast is still going on. Any further updates and I will add it.
UPDATE 2
There will be private matches possible, but no type of promod.
It will make servers and games uniform across the board setup and rule-wise.
How many players on a server is unconfirmed.
UPDATE 3
Now the webcast is talking about what has happened. You can go here to listen.
FINAL UPDATE
