Xbox one isn't profitable, Microsoft have armies of accountants that can play games with numbers to send whatever message they want to Investors. The "reserved" 2.1bn dollars in one quarter for RROD and made a massive loss that quarter, but then claimed 100k profit the following quarter. Its utter nonsense. They don't factor in r&d costs and other costs when proclaim a division is profitable.
It's safe to say, when you look at the big raw picture, Xbox never made Microsoft a dime, just rented the books, they are just masters of covering that up to keep shareholder happy. I want to know how that fits i with SARBOX
