ethomaz posted this earlier, and I think this is important to understand this confusing situation
A "normal" number of 360s to have on the shelves would be something between 1.5M and 2M (considering previous years).
According to VGC, at the end of last year there was 2.3M 360s on the shelves (let´s assume that the over 66M quote is 66.0M).
A lot of people say that those numbers are impossible, and that the 360 is undertracked (and buy undertracked I presume "big" numbers not just 100k) in other areas outside of US, these people are dismissing one factor I already said elsewhere.
There is no way retailers/MS expected to sell just 50k more 360s in December(5w) then they did in November(4w), we are talking about the US market. That is why it would not surprise me if, in addiction to those 1.5M-2M "normal numbers", you could easily add 0.5M (or even more) consoles that were wrongly shipped/bought by retailers based on miscalculated demand.
Two aspects that help the "undertracked in other areas" theory is the fact that the 360 is still 0.4M overtracked in US in December (according to NPD), and the MS quote about "over 66M", it could be 67M or more
My point is that anything between 2M-2.7M would not surprise me if you take into account the surprising US numbers the 360 (and the other 2) had in a December month where bigger numbers where expected (educated guesses VGC, Pachter, and EDDAR).
P.S. It bugs me that we still have to wait for the Nintendo graphics to really know more about this, when both Sony and MS could easily do the same even if they had slightly different numbers.
