this is quite silly, People buy Wii fit for Wii fit. The other balance board games are for the most part cashins because people who have a BB would not mind having other games to play on it (We Ski is prime example) I would think VERY few people bought Wii Fit for the balance board only.
If you are going to count Kinect Adventures, then you must except the fact the Wii Sports has sold 70 million. But most of you want wanting to count KA, aren't willing to do the same for WS.
I am not tracking however that WSR is heavily bundled. Also the only ones I have seen you pay more for WSR bundle (meaning you are not getting it for Free)
I count WSR, but do not count WiiSports or KA.
If anything WS has more say since it sold 3 million stand alone in Japan.
End of 2009 Predictions (Set, January 1st 2009)
Wii- 72 million 3rd Year Peak, better slate of releases
360- 37 million Should trend down slightly after 3rd year peak
PS3- 29 million Sales should pick up next year, 3rd year peak and price cut
