The only thing Nintendo needs to do in reguards to WiiMotionPlus is 2 things. Release a WiiMotionPlus specific game and announce the WiiMotionPlus specific details of Zelda Wii. Those two things will hype WiiMotionPlus to the limit the peripheral needs from the Nintendo side. Third parties should be picking up the slack for the rest. As we've seen, they most likely won't.
