N64 rumble pack ... An inexpensive device which can be attached to a standard controller ended up having optional support in most games released for the N64.
I could be wrong but I expect something very similar from Wii MotionPlus ... Certainly, most games will never require it but it should see a high level of support with some developers even (potentially) providing additional controlls to take advantage of it.
