It's an interesting metric, and I'm sure Wii Fit drove some sales - but similar to simply looking at attach rates, I don't think it delineates the Wii Sports/motion control effect from software sales or more broadly for any system, a large installed base - developed by numerous/other factors - driving software sales. Presumably people don't need to register Wii Sports with Club Nintendo.The metric is that Nintendo looked at what games were registered along with a new system registration through Club Nintendo, and used that to determine what game the system was purchased for.

Wii Fit and Wii Fit Plus are both at the link along with the other "big" sellers on Wii. Wii Fit/Plus were clearly the major "system sellers" in all regions as shown by this metric.
I don't think these titles that sold astronomical numbers (NSMB, Wii Fit) on the Wii, can necessarily be counted on to actually drive a successor's sales substantially in isolation - as I think their sales were a function of the system's popularity to a (large) extent. A similar scenario can probably be applied to titles from the PS2 era, Gran Turismo, Final Fantasy.
That's without looking at successors to these breakout hit style games (Brain Training, Nintendogs) on successor systems - that didn't manage to drive sales substantially.
Do you expect Wii Fit U to sell like its predecessors and/or to substantially drive sales in a sustained fashion?
