Agreed, there really needs to be some type of official controller. I'm assuming whatever input device they come up with be bundled with Valve's own Steamboxes, and available for purchase separately. Also, I wonder if there are agreements for other hardware manufacturers to bundle that same device. This way, all games have a standard controller to develop towards. Everyone loves the Xbox controller, not only because it's a solid device, but because it's the standard controller for PC gaming. Most games are developed with it in mind, so it's typically plug and play. For this reason, I'm going to assume Valve launches a controller that has a similar configuration to the 360 controller, so all the previous games designed for the 360 controller are ready to go. However, it'll probably have some misc tweaks, like buttons to perform certain tasks within the Steam software, and perhaps a touchpad, pull out mini-keyboard or improved motion controls. I'm not going to worry about people going to Radio Shack or Best Buy and randomly shopping for controllers. I think Valve has this under control, and we'll have THE controller, and third party controllers, similar to any other gaming console.
