Well I guess there's no way the Wii have sold 20million units by the end of the year if it keeps selling like that, it needs more than one million units sold per week to reach that goal and this week's numbers are on the 600-700thousand levels.
Unless it is true that nintendo has a lot of wiis stockpiled for this holiday season there will be no 20million wiis sold, but for the end of the fiscal year it will reach that goal easily.
