This excites me. Valve's bread-and-butter, as a gamedev company and not a game reseller, uses a pointing device. FPS games and Dota are both genres that do far better with a mouse.
Obviously, supporting gamepads will get the vast ocean of console-like games into the living room just fine. But for games originally designed for a mouse, a gamepad is a pretty sub-par experience. Do they have some new control device planned? Please? Pretty-please?
