What the Surface team is confirming is that both the Xbox 360 Controller for Windows (a wired USB controller) and the Xbox 360 Wireless Gaming Receiver will work with Windows 8 RT and Windows 8 Pro. The former would allow you to connect the controller via USB to the tablet and it would work just fine, and the latter would allow you to use an Xbox 360 wireless controller by connecting the gaming receiver to the tablet via the USB port.
Both have been available since Windows XP and I agree this should have been expected and it's nothing new.
