Erm...it's the other way around. With MotionPlus Nintendo was the first platform holder to use a gyroscope in a controller. It's also a current-gen gyroscope (using MEMS technology) unlike the gyroscope in the Move controller which is a last-gen gyroscope (using IC technology). The weird thing is that the Magnetometer in the Move controller uses MEMS technology, but as far as I understand it they wouldn't need to use a Magnetometer if they used a MEMS gyroscope in the first place. Maybe it was cheaper to do things that way..? Only reason I can think of.
The RemotePlus just has the MotionPlus expansion built-in to save you buying a seperate MotionPlus expansion. There's no difference between the RemotePlus and a bog-standard Wii Remote with a MotionPlus expansion plugged in.
