Sony's slow console sales and dismal gaming division performance has not slowed the company down as a whole, with the company posting a record high profit for the past year. Sony's net profit has done a massive tripling, largely due to huge sales in the digital camera and laptop markets.
Other aspects of the company helped profit too, such as them selling off or shutting down parts of the business that weren't "core", a common tactic that many large companies take. Given that the PS3's manufacturing costs have gone down since release and will continue to do so most likely, next year may be a different story for the PS3.
