@Jaaau!
It is the perspective of a programmer because I can recognize what is going on on the screen and which parts require a lot of power to do. Also, both Epic Games and Guerilla Games have been very open on their engine, so yes, I do know a lot about the development process on both studios. GG even posted a few CPU dumps on what the Cell processor was doing for a few scenes. I am trying to present it as simplified as I can. If I get too technical, then half the people here won't be able to understand it. It's meant to give you an overview. If you'd like more technical information, I can send you a few links

Actually, it hasn't really been reduced. Sony added in-game XMB which kept it the same. Any reductions they made were canceled out. On developer forums such as beyond3D, 43MB for the OS alone (not including framebuffer and junk) is the latest figure by people working on PS3 games. Not really NDA since Sony updates it in press releases as well.
Good news Everyone!
I've invented a device which makes you read this in your head, in my voice!
