Exaggerated or not, there's bound to be some developers (including Nintendo) that will implement a full range of motions to use for their games using the Revmote. Maybe we exaggerated that thought because of all the moving they did in the video shown at TGS last September. And even if there's no motion needed, fans are going to move anyways, I've seen people twitch just playing with a regular controller. The Revmote can measure its tilt and yaw, unlike a mouse which only moves on a flat surface, so there's got to be some arm motion involved.
