There's a good interview with Gabe Newell, co-founder of Valve, up on Game Informer. Gabe talks about Steam and how it sits in the market today, along with products in development like Half Life 2: Episode Two. He also talks about future development on consoles, with their first attempts having met with good success on the Xbox. He remained critical of the PS3, asserting that Sony should call for a “do-over” with the whole thing. Interestingly, he said quite the opposite of the Wii.

The Wii is certainly no slouch. It has been doing amazingly well since its release, and even up until now is selling very well. Last month, it sold more than the PS3 and Xbox 360 with 425,000 sold.

That success is not lost on Valve. He talked about the hardware of all three consoles, and the criticism Nintendo has faced over the Wii's less-than-stellar components as compared to the PS3 or 360. That presents a challenge, he says, but in the same breath mentions that not developing for the Wii is not helping them:

You can’t think of it as graphics, CPU, texture bandwith scaling, you have to think of it as more fundamentally, and I think it’s more valuable. I think it’s more interesting than just graphics chip – CPU combination. It’s the machine I have at home. The fact that we don’t have anything in development on it even though it represents big opportunities as a whole, it’s an obvious hole in our strategy.
The interview also mentions newer technologies like DX10. It's a good read.
