The hardware had been sold for less than cost since its release in November 2006, and high manufacturing costs made the console a continued money loser until just recently.
In late 2009, Sony released a "Slim" version of the PS3, which has more streamlined internals, and a cheaper price tag which led to an increase in sales. Manufacturing costs continue to fall as well, and it appears that Sony will reap the benefits of a profitable fiscal year.
For the fiscal year ended March 31st, Sony lost almost $900 million USD for their games division. That will change this year. "For this year we expect to be able to generate at least double-digit profits," adds Oneda, via BusinessWeek.
