i have 3.
And Wii play sales are just short of 15 million. Which would be about 45% of Wii owners with at least 2 controllers.
However there will be a large number of people with extra controllers via the usual route of buying them alone.... I have no idea what that would be, but at least a further 15%, so 60% minimum.
