I don't think the guy is an idiot, I think the vast majority of gamers these days are. Most of the stuff he's saying about framerate isn't his opinion, but what they've researched and found to be the common opinion among gamers and reviewers. The whole idea of making a public statement of no longer making 60fps games still bugs me though. It's a business decision though, and thanks to joe retard who wants pretty graphics above all else, we lose our slick 60fps games. That's not to say I don't love me some pretty pixels, but not at the cost of everything else.
I think really it matters most in faster paced games. Have you ever run Quake (any of the uake games) in multiplayer on an old computer that got a bad framerate? It's shit, and tweaking it to look ugly but run better makes for a much better gaming experience.
For Ratchet and Clank games I can see a (solid) 30fps working fine. I've never played Resistance 1 or 2, so I can't comment on their framerates and if they really need 60 (I'm hearing that they were 30 anyway, so I dont even know.) Solid is the important part there, and this guy says framerate is still important to them, they're just not gonna push for 60 anymore.
EDIT: Like Ghandi said, I don't think many people focus on framerate at all unless it slows down and becomes a problem. But when you pop in a console game and it's running at 60, you may not think "framerate", but it feels smoother and plays better for it (depending on game type I guess). When I hear that a game runs at 60fps, I automatically think "these guys care more about gameplay than graphics", and I respect them more for it.
