Nintendo Wii gets a remote upgrade?

As of today Nintendo has announced that the Wii remote will soon be capable of true 1:1 control via a new remote add-on for better motion performance.
the add-on is called the Wii motion Plus and is simply a dongle that snaps on to the bottom of the remote where the nunchuck normally attaches. And I know what you`re thinking and we can all rest easy. Nintendo will be issuing a new wii jacket to fit the new device aswell.
Also the device seems to have an extra pass-though port at the bottom to attach a nunchuck.

The add on is said to increase the accuracy of the remote and give it a better sense of your hand and arm position in a 3D environment. Nintendo claims that this will give the Wii true 1:1 control for a more genuine and immersive experience.
