After 18 to 24 months (1/4 to1/3 of the time before most consoles are replaced) it should be clear how popular a system is and the sales trend should be very predictable. At this point in time the Wii is selling at a rate of (approximately) 30 Million units per year and is still limited by supply, so it would not be unrealistic to estimate demand at between 35 Million and 40 Million Wii systems per year on average; at 40 Million systems per year the Wii's non-holiday average sales per week would be 600,000 units.
