ok, taken from January of this year from Gamespot.
"According to analysts with Reuters Estimates, Nintendo will post an operating profit of 120 billion yen ($1.16 billion) and a net profit of 74.2 billion yen ($720 million) at year's end."
6 months earlier in july from gamespot about sony:
"However, in the games sector, sales fell 15.9 percent to 105.4 billion yen ($943 million). Additionally, the division posted an operating loss of 2.9 billion yen ($26 million). Software sales increased but not by enough to offset the drop in hardware sales."
Another fact from a gamespot story 4 days ago on microsoft:
"Not only was the Xbox's division the only part of the company to bring in less revenue than last year ($525 million compared to last year's $634 million), but it also increased its operating losses for the quarter from $138 million to $141 million. "
From a more recent story on SCE as a whole which includes more than the PS2 division also 4 days ago:
" The idiom "you have to spend money to make money" holds true for SCE, as the company spent millions on marketing for the PSP and on research and development for the PlayStation 3, yet it still made a profit of 8.2 billion yen ($71 million). Last quarter it took a loss of 5.9 billion yen ($51 million). "
Recent Nintendo News from earlier this month, no clue why it comes up under madden:
"However, just because Nintendo isn't making as much money doesn't mean it's not making money. Net income--aka profit--for the six-month period was 36 billion yen ($316 million), way above the 19 billion yen ($167 million) estimate in May but lower than the 46.4 billion yen ($407 million) a year earlier. "
Seems to me from this information, Nintendo is doing pretty god damn good compared to the others.
