Aaron Back says Sony is paying serious attention to the profitability of its Playstation business. He cites IHS estimates of Playstation 4 costing $381 to make and the retail price set for $399, in contrast to the Playstation 3 which cost Sony $100 more to make than the retail price. Sony's Playstation business is expected to post operating loss of 27 billion yen in the fiscal year ending March 2014, with profits of 37 billion yen the following year, and 65 billion in the year following that.
