No. Nononono. Sony has like four segments that are more profitable than gaming.

No, PS4 isn't saving Sony by itself. 

What he said.

Don't they do insurance as well?

Lol, their playstation console doesn't mean a whole lot to them. Their cameras/sensors and insurance are worth more to them. If they lose that business they're in big trouble. It is their bread and butter. The mobile division alone cancels playstation profits.

Doubt it

Which ones?

Probably, as the brand would be so broken the market would have broken it up and sold the pieces by now or shortly...

Sony are saving themselves by making good decisions. They are dropping bad investments and putting more money where they have more revenue. PS division is helping ( with money and revenue) but with it alone they don't stand a chance.
