For all the Sony fan boys, here is a summary of what Gabe said in the interview (and I don't think he hates PS3):
He explained that when he expressed a negative outlook on the 360's architecture everything was about super fast single cores. But as time went on, Intel shifted her focus to multi-core, and the 360 was released. And so learning to use more than one core was important now, because it would not only benefit the 360 but it was applicable to PC gaming going forward. So the months they spent working on 360 was just as beneficial to PC development and future development. Learning to use multi-core CPUs is something that had to be done since Intel and AMD both are pushing in that direction.
On the other hand, he was just as negative about the PS3, the problem is, it does not make business sense for him and his team to take the time to learn how to program games for PS3. They could be working on new games, or doing other things, rather than spending months on end adapting to an architecture that right now and for the foreseeable future is and will only be in the PS3. This is especially true when you consider PS3 install base, and the fact that not all of that small number is PS3 exclusive customers. It is like asking if they want to invest 6 months for 2 million possible customers, or 6 months for 30 million possible customers (PC and 360 development go hand in hand).
