The article does not mention anything about exchange rates - since the PlayStation is not manufactured in the US and the article mention all amounts in dollars [the Yen strengthened considerably against the Dollar the last year or so] - I would take the amounts with a pinch of salt.
The other possibility of course is that they converted everything from Yen into Dollars - but did not mentioned it.
