Yeah Valve's stuff works good on PCs.
Doesn't work so hot on PS3s, though. Its not the PS3's fault, despite Valve's claims. That's kinda the point that the Gearbox guy was addressing. So many devs have now demonstrated that working on the PS3 is, while perhaps different, is not as hard as some devs (i.e. Valve) like to pretend, and is, in fact, new and thus cool.
Parallelism IS the future of computing, and any serious developer will embrace that change. You don't have to like the PS3 to acknowledge that its a cool architecture, with a lot of potential. And yep, I'd say that's a proven fact, at this point. That's basically all the Gearbox guy is getting at.
Valve's public statements about the PS3 just look... ignorant, at this point. They have no backing. They may as well just come out and say "we stand to make more money from claiming exclusivity via 'ease-of-use', because MS pays us extra to do our exclusives that way".
