Valve CEO Gabe Newell:
We’ll come out with our own and we’ll sell it to consumers by ourselves. That’ll be a Linux box, [and] if you want to install Windows you can. We’re not going to make it hard. This is not some locked box by any stretch of the imagination. We also think that a controller that has higher precision and lower latency is another interesting thing to have.
I’m going to take a guess and say an ‘official’ Steam Box should make it ways out by the end of 2013, coinciding nicely with the launch of next-gen consoles by Sony and Microsoft. We could have a potential PC (Steam) vs. console (Sony, Microsoft) vs. mobile (iOS) race ahead of us, fighting for attention in the living room. I think iOS mobile gaming will inevitably stay strong and get stronger, but all bets are off in terms of how consoles and PCs will end up two years from now.
