Looks like Toshiba's Cell processor ambitions didn't quite pan out -- Japanese news sources are reporting that the company's selling its Nagasaki manufacturing plant back to Sony for 50 billion yen, or roughly $597 million in US money. Considering that Toshiba originally purchased the semiconductor facility for 100 90 billion yen (then $835 million) back in 2008, it seems like Sony's making out like a bandit here -- and it may have just found the perfect place to build more CMOS chips for its high-end camera lineup, too. Sony reportedly told the Nikkei Business Daily that it may repurpose the facility to produce HD image sensors for cameras and smartphones. What will happen to the chip that launched 40 million PS3s and a graphics co-processor or two? With any luck, we'll find out at CES 2011 quite soon.
