There will be no dedicated servers for the pc, confirmed on bash and slash live cast with 402. That's too bad I was thinking about returning for mw2 but now il just play xbox if there's no dedicated servers.
I think the no dedicated servers is just a rumor as of now. This article says that it may not be supported, but It really is Call of Duty 4 only reason for it lasting as long as it has. So many big clans like edgegamers supporting servers.
My personal thoughts are, if they dont at first they will because it will hurt them to bad not to.
I think on release date you will see dedicated servers.
