It appears Sony isnt quite done selling off assets in a bid to reverse its financial losses. Just weeks after it sold its VAIO PC business, the company is reportedly in talks to offload another one of its properties: its former headquarters in central Tokyo. The deal could net Sony more than 15 billion yen ($146.5 million), adding to the $2.3 billion it recouped from the sale of its New York and Osaka buildings last year.
