So MS decided they didn't need to ship more units because I don't know... they don't want to sell Xbones... magical logic here
Fact: While Sony manufacture 2x PS4... MS is having a hard work to manufacture 1x Xbones... that's just a example and it can't be 2:1 but 3:2 for example.
Let us assume that MS shipped as munch as Sony. Sony sold 2.1 M PS4 worlwide compare to 1.5 M Xbox One of MS. So are you saying that demand for Xbox One is near 600 K less compare to PS4???
Maybe this is not that fair let us take the US which is MS strongest territory, 1.25 M PS4 vs 0.94 Xbox One. So are you saying that the demand for Xbox One in his strongest territory near 300 K less than the PS4???
That is of course assuming that the Xbox One is shipping at the same rate with the PS4...
