"We're confident in some things that customers want," Valve's Greg Coomer, head of the small team that designed and developed Big Picture mode, told me in his office. "They want a full-screen experience. They want to be in the living room. They want to use a game controller. They wanna have a social gaming experience. And we have this platform that lets us ship a significant portion of that experience."

"What we really want is to ship [Big Picture mode] and then learn," Coomer said. "So we want to find out what people value about that. How they make use of it. When they make use of it. Whether it's even a good idea for the broadest set of customers or not. And then decide what to do next.
"So it could be that the thing that really makes sense is to build the box that you're describing. But we really don't have a road map. And we think we're going to learn a tremendous amount through this first release."
