If it's any help to anyone, buyers intent in the US for consoles among adults is 23% this year, down 2% over last year.
Also folk should take into consideration, according to our numbers, Wii has sold a vast amount more than they have shipped this year, meaning that a lot of stock in Q4 didn't sell (overshipping?) (or we're overtracked) either way it doesn't paint a pretty picture for the wii, either it did considerably less last holiday than their shipments lead to believe, or sales this year really have fallen off a cliff.
In fact we only have Wii sales for Q4 last year 1.7 in Wii's favour against the 360 despite the 2.5M gap in shipments.
