Third and Final (For Now)

Well, I didn't see that coming. The final Valve announcement is indeed a Steam controller. The most interesting features are definitely the touchscreen in the middle and the two trackpads, instead of joystick or other, more traditional directional input method. Sadly it is still a part of the beta, like the Steam Machines, so you to enter the beta you have to have a different controller already. Really would have been nice if this were launched today, so it could be used to count toward the beta, but Valve never asked me.
