This is a grey area, I guess...
I do not believe piracy is affecting most consoles too much. However, policies toward any console/portable system and public relations may play a larger role in the success of a console system and how many people will pirate games for it. I hope I do not sound too biased but I traded in my PSP for a Nintendo DS because I am under the impression that Nintendo's policies regarding the DS are far more friendly and courteous towards consumers than SONY's policies. Of course, the fact that the PSP's games are mostly the same old stuff people have played before and the excessive load times did not help either.
