Its at 2 million on 6 million machines in Japan (33%).
May be more successful in the west (35-40% in early 2009)...but 35%/40% is probably the upper limit on its attach rate, and worldwide I think its closer to 25-30%.
Wii really has no chance of selling less than ~50-60 million now, so even a 33% attach rate would be ~20 million games sold. At $90 a pop, thats almost $2 billion in Wii Fit sales. If Wii gets to like 100 million, 140 million, 200 million or whatever it is, the game could potentially be packaged with Wii later in life. Even a 20% attach rate at 200 million would be 40 million units.
My hunch is Wii gets to 80-160 million and the game has a 25% attach rate lifetime.
