Remember the news, I do not post links here 'cause you can find them easily on Google (search for "Sony's most profit division") and you'll find that Sony's profit comes from other divisions rather than gaming division (which is giving them losses).
The market is an ever-changing thing and if there's a company that adapts quickly to market changes is Sony, for example if they lose the format war it's fine maybe they lost money with the research of Blu-Ray but they can profit by selling millions of HD-DVD players in very short time to recover market-share (remember Beta vs. VHS battle?). What if they lose with the PS3 and the PSP? Not the end of the world for Sony, they can develop a new console by avoiding mistakes made this gen and get back to the fight.
