I'm expecting Wii, DS, PS2, PSP and X360 to all be down a fair bit in the USA over the next two months, with PS3 basically flat. As has been stated previously, Walmart, Toys R US, Best Buy, Game Stop, Amazon, and Target have all been offering steep Kinect and Kinect w/ X360 discounts over the past few weeks. The problem is Kinect made X360 do almost 1.4m in the US last Nov, which was a historically huge rise from October. A more normal October to November transition for X360 would be around 850k-1m. Same goes for Wii, although putting Zelda just ahead of Black Friday should assure a slightly bigger multiplier effect from Oct to Nov since all the big HD software is out by mid-month vs. late month for Wii.
3DS on the other hand should see fairly amazing sales for Nov-Dec relative to how poor its figures were into mid-August. I just re-looked at my models and 3DS / PS3 both look like they'll get to around 14m-14.5m for the fiscal year which is pretty good.
Next year should be fairly similar to this year but down for the existing consoles.
For those saying wait for NPD, Iwata was citing an "NOA report" in saying Wii was up in the first three weeks of October vs. 2010 in the US. To me that's either data from Walmart / Target and major retailers or preliminary figures from NPD which are available to the manufacturers.
Year end figures for the US really should be 6 / 6 / 5 ish this year for the consoles vs. essentially 7/7/4 in 2010. Amazing to think that we're going to have two US consoles at / nearly at / above what PS2 sold pretty soon, and in one generation. Wii will be 6-7m behind PS2 in the US by year end, with X360 15m-16m behind roughly.
