Games leak earlier on consoles because they only have one layer of protection (Xbox firmware) and can't implement much in the way of exotic measures while PC games have tons of options. Also, the certification process probably creates quite a few more gaps for leaks. According to this is 2008 article that explores piracy [http://www.tweakguides.com/Piracy_1.html], the few numbers piracy sites have given show significantly more illegal downloads of PC titles than consoles. That makes way more sense because console piracy is a long, sordid affair involving hardware tweaking and really specific firmware modification that either costs a ton of money to outsource or can easily break a system.Baresark said:No one knows the exact numbers of piracy. That is a belief that can't either confirmed or denied. My main point was that console games leak early consistently. PC games usually have to at least wait till release. Piracy is rampant on all consoles that you can pirate on. The funniest part of this for me though was that MS pulled Gears of War 2 on the PC because of piracy, but all the Gears releases have been pirated significantly since that statement was made, and the games have consistently leaked up to a month early.
Regardless what effect piracy actually has on the industry, game developers just have a way larger economic incentive to develop for consoles because they consistently outsell PC versions by more than 10 to 1 (for example, Call of Duty: Modern Warfare 3 [http://www.vgchartz.com/gamedb/?name=call+of+duty%3A+modern+warfare+3&publisher=&platform=&genre=&minSales=0&results=200] sold 14.83 million on Xbox 360, 12.60 million on Playstation 3, and 1.55 million on PC). That's the real reason PC versions don't get made; because they usually don't sell enough to justify the development cost.
