I'm not sure about soundness of good old Sega net income. 

 :) Double Fixed.

Interesting.

Thx celine. :D

One thing to note is that Sony and MS report operating income for their divisions, not net income.

This will be particularly pertinent for 2008 as Nintendo took a $900 million writedown on their net income, which is not reflected in the operting income. So even if Sony or MS show an operating profit for their division, they may actually have a net loss and it may be impossible to tell from the reports. 

Another thing to report is that these sort of reports are built on standards, rules and regulations that are made to make them as true to reality as possible, but that there is no way to count any of those numbers as true. THey are more like guidelines to what the result might be.
