Considering the vast majority of current Big Picture games use the Xbox360 controller, and that they'll probably already worried about getting enough content working on this device, I highly doubt they will do something so different as a Rift + Wiimote and the like. My assumption is Rift will be supported, but primary controller will be something extremely 360-like. If not made by Valve than by someone that already makes 3rd party 360 controllers.
