People are missing something important here...
Sony in November sold 250k more units in US than Xbone.... and even now the Xbone seems to be outselling it but a few hundred units (VGC shows less than 100k diffeence per week).
So if the console that sold more overall is getting SOLD OUT and the console that sold less is available... how that make the people thinks that MS shipped more units to US?
The issue here is the crazy demand of the PS4.... even if Sony shipped another million to US they will get Sold Out even if they ship only to Gamestop.
