Microsoft i believe definitely is questionable in this regard, in that it's widely known that the Xbox brand was originally conceived as a trojan horse to keep the PlayStation brand from ever becoming a threat to Microsoft's real bread-and-butter, the Windows brand. They also showed it because they clearly designed the original Xbox with 0 regard for profitability
They seem to care more, now, since the 360 corrected many of the original Xbox's errors, but still they haven't hesitated to pile on the deficit spending against certain problems (like the $1.5 billion set to fix RRoD), but i still don't know what they're really after.
Sony certainly sees gaming as integral to their business by now, i would say. Like others said, the PS2 was their main moneymaker back in the day, so they know well the benefits of holding the dominant gaming platform. They're going to prioritize it in the future.
