Wii Motion + is full 1:1 tracking.

Technically, Wii Motion + only tracks orientation (3 degrees of liberty). You can still call that 1:1 or not, depending on your definition.

A system with an external camera like the Sony wand thingie can track orientation and shifting at the same time (5 or 6 degrees of liberty, not sure about depth/Z axis).

According to this, it does orientation and position.

[video was here]

No, it doesn't. Gyroscopes can only provide you with orientation changes relative to a starting direction.

That video is about a specific piece of software from a third party developer that tries to infer the position of the wiimote from its orientation (and possibly from accelerations) by knowing the kinds of motions you're going to perform and from biometric data such as the angles and size of the human arm. The guy in the video says so himself, well not in these terms, but thats what he means.

If you were to slowly parallel transport the wiimote around (not changing its orientation at all), that software wouldn't be able to tell. It would also go completely wrong as soon as you twist your wrist around or in general you keep your arm articulations in a different stance from the one they calibrated the software for.

It's still only 3 degrees of freedom, there's no way around it.

The Wii remote already tracks linear acceleration along 3 axes.  That is three degrees of freedom by itself.

Wii Motion plus will track rotational motion.  I am unsure of how many axes it will track, but I would assume all 3 axes.  That would bring it to 6 total degrees of freedom.
