Someone please correct me if I'm wrong, but my understanding was that Sony licenses the discs to the publishers, so in fact to Sony the discs do cost next to nothing (in which case you'd want to include the price of developing/manufacturing the console to make the discs not "cost nothing," not the cost of developing the games, which is on the publisher).
