The header of the page states, "The Steam Universe is Expanding in 2014", and goes on to say, "Last year, we shipped a software feature called Big Picture, a user-interface tailored for televisions and gamepads. This year we’ve been working on even more ways to connect the dots for customers who want Steam in the living-room."
In concludes, "Soon, we’ll be adding you to our design process, so that you can help us shape the future of Steam."
To top it off, a gamepad can be seen on the floor, with a countdown at 59 hours as of the time of this article.
