Before the PlayStation 4 is released, it looks like Sony are cashing in their bottles and cans to raise some money - the Japanese company have just announced the sale of their 13% stake in Japanese mobile gaming company DeNA. Nomura Securities are the recipients of the sale, estimated to be 40.9 billion yen, or approximately $440 million. The announcement from Sony has said:

Sony is transforming its business portfolio and reorganizing its assets in an effort to strengthen its corporate structure. This sale is made as a part of that initiative.

It's a strange move, as DeNA are one of the world's largest mobile social games companies, with over 40 million users in Japan alone. With Sony wanting to push the PS4 in a more social direction, and with Sony being a Japanese company who are loyal to their own people, why the sale of shares in a top mobile social games company, now?
