While companies are required to report certain financial numbers, they don't necessarily need to break down sales of specific products within subdivisions.

In other words, Microsoft may be required to report revenue from their gaming division, but that doesn't mean they're required to specifically report how many Xbox One consoles were sold.

MS stopped releasing those figures. Their official reasoning was that it doesn't really matter since the money is in the software (true). The real reason IMO was because they were embarrassed.

Is every HN reader a Microsoft or Sony shareholder?
