Sony's cutting divisions that lose money, like their PC arm, so that they can focus on areas that do make money, like their TVs. While PS3 wasn't that profitable, PS2 was, and the PS4 is positioned to reach profitability much sooner than the PS3. Kaz Hirai's been quoted stating that Playstation is a core business for Sony.Stephen Elop, the MS exec currently in charge of the Xbox division, has been quoted saying that Xbox is not "critical to the company's strategy", and suggesting that they sell off the Xbox division. He pointed out the obvious that the Xbox brand isn't profitable. IHS forecasted that the Xbox division lost 1 billion in 2013, down from an earlier 2 billion dollar loss forecast. A lot of MS investors, agree with Elop and would prefer that Surface, Xbox, and Bing, were cut out of the business.Meanwhile, Nintendo has remained profitable, despite the Wii U struggling, due to strong 3DS sales. They're mixing it up with more 2nd party software development, since they know Xbox One and PS4 have an advantage with 3rd party developers, and they will likely turn a profit on the Wii U by the end of it's life-cycle. They're not dominant, but profitable in their niche of the market.
