If it is true they kept 500 000 wii's stockpiled from march to now, then there will be 7X500000=3.5 million wii's for thanksgiving/christmas, including the normal 1 million that would be 4.5 million, if they manage to sell all those wii's in november/december, and if they manage to break the 12 million barrier before november, they would have a tremendous 16.5 million sold units by the end of the year, if not more.
And I can imagine Nintendo releases some additional stockpiled wii's for the launch of Dragon Quest Swords in Japan.
