Some people here don't seem to get the point of the article... -.-
The point is: with the PS3 Sony developed a console without listening to their own devs (and 3rd party devs). The result was a console that was hard to develope for and because of that we had many devs being pissed (mainly 3rd party devs). With the NGP on the other hand Sony worked together with their devs, asked for their opinions and so on. The result is console that's pretty easy to develope for, and that's (btw) not just what Sony devs say, Kojima and Sega said this as well.
