Ewwww Punkbuster, Punkbuster is the hackers worst nightmare >.< you can't code a hack to bypass it (easily) unless you have a shit ton of experience, nor can you post a public hack it will be detected in a few minutes or days. <3 Steam, easy to bypass, and not greadt about detecting hacks ^^.
I bet it will be on steam 100%. Which is gonna make the game complete shit IMO. Im glad they took advantage of Iw fail game and made Dedicated servers that made them my new fav company. Iw now can smd. But i still wont get on pc never will buy a game on the pc because how fail mw2 was. I will be buying on xbox 360 and prob buying a jtag.
