I doubt the magazines are losing sales because this demo got posted early. It would show up on the web sooner or later and the people that are here reading these news sites and downloading it weren't going to go buy the magazine for the demo. The people buying the magazine tend to be people that use it for their main gaming info source or people that have slow connections and would rather get the demos on CD. Personally I subscribe to CGW but picked the subscription WITHOUT the CD because I find them to be a waste. I never ever find anything useful on them because they've been on the web for a while. I wish I could get PC Gamer without the CDs or I would. Those CDs just gather dust and eventually end up in the trash.
