Earlier this summer, Sony closed another fiscal year of being in the red, but it's starting the 2010/11 ledger with its quill dipped firmly in the black inkwell. For the quarter ending June 30, the Japanese megacorp clocked up ¥25.7 billion ($293 million) in pure, unadulterated profit off the back of a ¥67 billion operating income. When you compare that to the performance this time last year, a ¥37 billion loss, you have to agree that the Stringer purse-tightening program seems to have delivered the desired effect. The primary drivers for the current resurgence are pinpointed as the PlayStation 3 and Bravia lines (frankly, we consider the two utterly inseparable), and Sony's feeling so buoyant about it all that it's revising its projection for the coming year's revenues upwards today. The good news is tempered, however, by the threat of a rising Yen, which has already claimed Nintendo's profits as its first victim.
