If games consoles weren't a profitable business Sony would have dumped PlayStation by now. For anybody taking notice, they've been downsizing/refocusing the less profitable businesses (e.g. TVs, cameras), expanding their profitable businesses (semiconductors, particularly CCDs) and completely axing their unprofitable/too-low-margin-to-be-worth-it business without (Vaio).
Kaz Hirazi recently said "
It is likely that PS4 will become the platform which exceeds the profits earned with PS2". The recent $78 loss for PlayStation was attributed to the PS4 launch and shutting down some old MMOs. Sony ought to be nailing it for content delivery; PlayStation in the home and on the move, TV, movie, game and music studios and a TV, music, game and movie distributor. If anybody is looking to synergise through vertical integration of content production, ownership, distribution rights and delivery platforms, it's Sony.
And that's been his plan since becoming CEO in April 2012. They've now cut most of the fat and are beginning to work together. Prior to PS4 launch you would never have got the head of Sony Movie Studios at a game console announcement. Crazy times.
