COD 4 Pc sold less than 2 million units? Piracy is to blame?

[im_sneaky]

I would find it VERY hard to believe Cod4 pc and stalker selled in the same ballapark. that just doesn't seem right. I won't give a number but... all my intuition points to 2m being WAY too low.Cod4 had mad legs AND a great start.... 2m is way too low.
