Speaking about risks, Totoki-san explained that open-platform free-to-play games are becoming more widespread in the market, which could be a potential risk to the business.
Additionally games moving into the cloud, as an extreme example, could make physical hardware unnecessary. That being said. Totoki-san thinks it'll take much longer [than five years] for this to happen.
To counter these trends Sony can offer advantageous revenue share and the most immersive experiences possible. Third-party partners are very much supportive of PlayStation, and this will help Sony to avoid being affected by the risks mentioned.
In terms of opportunities, the largest one is the increase in network services performance and recurring business. The PS4's massive installed base and monthly active users in excess of ninety million are a strong point and leveraging the strength of the PS4 will expand the business and continue to generate profits.
