Here from the Sony docs.
"Sales increased 5.1% year-on-year (a 14% decrease on a constant currency basis) to 155.7 billion yen (1,588million U.S. dollars) primarily due to the favorable impact of foreign exchange rates. The decrease in sales on a constant currency basis was primarily due to a decrease in unit sales of PlayStation®2 (“PS2”), PlayStation®3 (“PS3”) and PSP® (PlayStation Portable) hardware, partially offset by increased PS3 software unit sales compared to the same quarter of the previous fiscal year."
