He said about the PS3: "Its strengths are obviously that is has a lot of processing power. Its weaknesses are that its processing power is locked away at the moment. But everyone's going to hit that wall across all platforms at first." As technology grows more complex, he sees the process of developing growing right along with it in complexity. With the onset of multiple cores, which will no doubt grow in number, it's harder to learn how to tap into the power of the system.
This, he's implying, is the problem many devs are running into with the PS3. Instead of pushing through the wall, they're giving up, saying it's too difficult. We say to them: don't give up! Keep trying and soon you'll learn the PS3 inside and out. Then we'll see some very impressive titles. Like White Knight Story. Whatever happened to that one?
