Also you can't play online, at official servers, with a pirated copy. I don't think more than 10% of PC user who bought it bought it for the single player only...

I'll be one of the people adding to those numbers.
I plan on buying it. (Yes, I'm behind)
Well-deserved I guess :S

 Well boohoo if more PS3s have sold in Japan, and Japan doesn't like FPSs.  I didn't realize we were selecting specific regions when talking about these sales.

I understand what you mean, but it's not like I was wrong either.  Compare worldwide sales of both consoles, and then compare that ratio to sales of COD4, and the PS3 is lower than it should be.  I understand why that is, because FPSs aren't popular in Japan, 360 hardware is largest in America where FPSs are strongest, but the point wasn't about why PS3 COD4 underperformed, just that it did.

 Its also possible to play the game and never notice these problems, plus the PC gamers have good servers and not P2P crap.  I can go a couple days and never notice any lag, or being screwed in kills, but when the lag starts its insane.  Along with the bad hit detections. 

Its like the information from one side is not regeristing with the other, this causes bullets to do no damage and players to warp and vanish around the map.  I have also noticed that the first couple bullets out of a gun do no damage, this can be seen with killcams, as i have walked behind a guy while he was being shot at and died with as little as 1-2 bullets hitting me.  While the killcam shows that the other guy fired over 10 rouds right into my team mate. 

On killcams you will also notice enemy troops on his screen that were not on yours.  I have also shot people walking into the room i'm in, but the kill cam shows that he walked in the room and got about 7feet in before i started to fire, while he was alomst behind me and was able to get an easy kill.

But when the lag is working for you, the enemy has no chance of living.  I use the P90 with stopping power and steady aim and i can get 20+ killstreaks without ever being shot at while running around the map like crazy.  By the time they see me i'm around behind them shooting them in the back.

Good sales, good game.

A lot of big budget games have had great success on the PC. Valve reported 158% sales increase in holiday 07 on Steam over holiday 06. That's pretty huge. Plus, you can't discount the fact that a publisher makes twice as much selling a game on Steam for the same price that they sell it on retail becuase Steam eliminates retail markups and just leaves publishing fees.

There's a lot left on PC... it's just not visible to NPD. NPD is basically just an irrelevant incidental number when analyzing the PC market.

Think again, I would say COD4 PC could very well be walking to +8 million copies, if not +10 million copies lifetime.

COD4 is on every single PC top10 chart still and is selling at a rate à la The Sims or WoW on retail. And when you consider Direct Download sales you'll see it being even bigger sales, because COD4 has outsold the Orange Box on steam since it's release, and I remember someone state that Steam accounts for 25% of the Orange Box sales (that percentage could be higher now), so if you do some thinking and check that OB could have near 2 million copies sold on PC, and 25% of that is 500k on Steam. So there is a chance that COD4 could sell 1million on DD alone.

Linking this article for a reason. In it Valve says that The Orange Box sold over 1 million on 360 and another few hundred thousand on PS3 (reporting shipped of course) but that the PC sales of the game were signifficantly higher than both combined by the double digit percentages. This implies that The Orange Box has sold well over 2 million on PC, and much of that was on Steam. So yes, as Shio said, CoD4 sales on PC could easily be well over 1 million now given how it's charted in sales tracking.

Lombardi goes on to say the PC market is healthy, but not in American retail sales. He says in other countries like Germany PC games outsell console games in retail and digital distribution is thriving.

Maybe I'm crazy but I think CoD4 is massively overrated, it's just an average shooter to me. Nothing overstanding or anything, and the graphics aren't THAT great.

Not worthy IMO...
