Bloomberg reports that Sony may be considering a new SKU for the PS3 with a larger hard drive. This follows closely on the heels of the announcement of the Xbox 360 Elite and the 120 gig Xbox HD. No other details are provided, in a story primarily about news of increased profits as PS3 sales continue to rise. " Chief Executive Officer Howard Stringer targets an operating profit margin of 5 percent by March 2008, about double the current margin. Tokyo-based Sony confirmed today that it will only sell a more expensive version of its PlayStation 3 game console in North America, a strategy it adopted for the European market to bolster margins. 'Profit margin will probably exceed 5 percent if Sony doesn't lower the price of PlayStation 3,' Hitoshi Kuriyama, an analyst at Merrill Lynch & Co. wrote in a report dated yesterday. He rates the stock a buy. Shares of Sony gained 28 percent this year, compared with a 0.8 percent advance in the Nikkei 225 Stock Average."
