The IR camera in the wiimote operates at 100Hz so it can relay information at 100fps, but Nintendo has been keeping quiet about the PixArt sensor on board the wiimote. According to the PixArt website, their fastest commercial sensors operate at 60fps, but only at low resolutions. The highest fps for SD resolution is 30fps, so I would assume that this is what the wiimote is capable of, although I cannot be certain. Can anyone give me a link that confirms otherwise?

The PS eye can also operate at 120fps, so it's still faster.

Also, there are already plenty of games available for the PC that have some form of head-tracking using TrackIR, and they are mostly racing or flying games.
