As of June 23, 2010, Windows 7 has sold 150 million copies which made it the fastest selling operating system in history with seven copies sold every second.
On October 21, 2010, Microsoft announced that more than 240 million copies of Windows 7 have been sold.
The numbers would seem to contradict your prediction. :)
