Yes someone has it... >_>
The thing doesn't even have a release date, come on be patient

Very much this.

The accellerometer can tell which way is up anyway though.... the reason a gyroscope is needed is because the accelleromter can't register rotation on a horizontal plane.... which is like if you hold the Wii wheel perfectly flat and turn it, it would not register (which is why you are told to keep it at an angle)

Really? I had no idea.

Speaking of the Wii Wheel...Nintendo will have to release a special Wii to accomodate Wii motion plus.  And the blaster for that matter...unless they're really just not planning it to be used with those peripherals.

It's not really needed for either of those tbh. No one would use the wheel except in a driving game, and a driving game is just fine without horizontal rotation.

As for the Wii zapper, there is no feasable situation I can think of where you would need the motion+ at the same time as the zapper. Sure there will be some games with both FPS and motion based actions needed, but any that require 1:1 motion would be better without the zapper anyway.

The Live Motion 2 video, not only are the movements tracked so much better, the fact that it can sense the difference between gestures much more easily, which opens up for even more complex waggle with Wii Remote.

Maybe grenades should be thrown with Wii Remote now instead of Nunchuck, without even pressing a button?

Wow the stuff that's demoed in that video is really really amazingly cool! =)

It can most of the time, but not all the time. It does so by tracking the gravitational force. When you swing the remote around, it can't really tell which of the registered forces is the gravitational force and loses the sense of direction (which way is up). Also, when you twist it in the horizontal plane, there is a force associated with the rotation. If the sensors are fine enough, it should be able to keep track. :)

The problem of using that in a driving game is that this measurement might not be precise enough to "remember" which way it was pointing to the TV (which should be for a game to look straight), that is why it is done at an angle because it is easy to track the gravitational force as it's always there and much stronger then a slight centripetal force.
