The Wired Controller Plus won't necessarily replace the Pro Controller as it lacks motion functionality and HD Rumble, but for the $25 price, it's hard to pass it up, and you can purchase one. The Wii sensor bar is quite simply a bank of powered up LED lights, it transmits no data to either the console or the Wii controllers. The LED lights are used as a reference point for your Wii remote, the Wii remote picks up the light emitted from the sensor bar and uses it to work out the movement of your controller.
