Nintendo maintains high demand for Nintendo Wiis by having limited supply. Look at the variations in Wii sales in Americas from week to week. It is like a yo-yo. I guess that Nintendo Wii shipments arrive every two weeks.
Production rates of Nintendo Wii manufacturing are increase up to 2.4 million Wiis manufactured per month and that amount is likely to increase. I guess it will be soon over 3 million Nintendo Wiis being mass produced every month.
