It seems every time we check in with Valve's Steam Controller, it's undergone another significant change. The last design, which added a D-pad of sorts and A/B/X/Y buttons, was more in line with traditional gamepads. Now, if an image making the rounds today is to be believed, Valve has dropped the four directional buttons in favor of a left-hand thumbstick.
Wonder where it'll end up with the design by the time we can actually order one of these controllers. Even more traditional? For better or worse, I can see myself getting one for the novelty factor alone, assuming the end product is still novel after all of these revisions.
