so far i think
2009 sales = 12mln(so far it sold 5mln+ this year)
2010 sales = 9mln
2011 sales = 6mln
2012 sales = 4mln
2015 sales = 1mln
End of life sales = 47-48mln(basically wii fit will end up in about 45-50% Wii owners as long as nintendo and 3rd party publishers will support it)
Wii Fit+ may be released, but not for the wii but nintendos next console. so i say that it will be released same year when Wii 2.
