I suspected it was production issues since their APU is larger than the PS4 one that makes sense that it would reduced yield. Not by much but enough to make it unable to spreads themselves out and still 'win' in their key market; the US/CA/UK. So they concentrated their units to try to score a early win on new generation hype.



It worked and they out sold the PS4 for a month in the US/CA/UK market but the bad press caught up with them and that initial win didn't mean anything in the long run. They also wouldn't have moved that many units in the tier 2 markets because they have little history there and the genres they're most known for (FPS) is not as popular in other markets. As well they really geared the XB1 to American markets with a lot of their app features and TV features.
