Here is a link to the Nintendo report: http://www.nintendo.co.jp/ir/pdf/2008/081030e.pdf
Nintendo combines Q1 and Q2 into a half year report, so to get quarterly sales you need to deduct the figures from the previous quarter (if anyone has a link please post it so I can go into regional detail)
At the end of June 2008 Wii shipments had reached 29.62 million, and the latest report shows 34.55 million Wiis have been shipped through September 2008, giving a worldwide quarterly figure of 4.93 million.

The forecast for the end of this fiscal year has been raised once again, it was originally forecast for 25 million Wii to be shipped for this fiscal year, but that was increased to 26.5 million last quarter, and up to 27.5 million in this report. This would put the Wii lifetime shipments just short of 52 million by the end of March 2009.
Given that the current rate of production is 2.4 million per month. The minimum number of shipped consoles for the end of 2008 should be 51.95 - (2.4*3) = 44.75. However as last year, Nintendo will almost certainly be shipping a number of consoles by air for December, that would normally have been shipped in January. Going by my estimations from the differences in shipping and production rates, last year about 2-3 weeks worth of stock was shipped which at the time was 900k to 1350k.... however with the increased production, this year 2-3 weeks worth of stock is 1200k to 1800k
So using those numbers the shipment figure for the end of the year should be between 45.95 and 46.55 million. Take from that what you will regarding sales to customers, it depends on how high you think the demand is for how sold out the Wii gets. It is not likely to be sold out to the same degree as last year when the difference between VGC and shipments is about 900k.
