Valve has been developing a Linux-based, Steam-powered gaming console for over a year now, and after teasing us with a countdown timer, today is the day of the big unveiling.

They threw us a curve ball, though: They'll be unveiling THREE things this week.

The first of them, SteamOS, has been unveiled. The countdown on the teaser has been reset. The second piece of hardware will be unveiled on Wednesday.
