i believe i remember something about Sony making $2 billion with the Playstation 2 brand, which, for the number of consoles sold, and the number of games sold is not that much (Nintendo will have probably made $2 billion with Wii brand in about a years time)
it is possible that the $2 billion might have only referred to something specific like Sony hardware + Sony software (ie not including 3rd party licencing fees/any fees for 3rd party perephrials) but i am not too sure.
I think it was also estimated Sony spent $2 billion on research and development etc (everything spent before it lauched) on the PS3.
basically Sony are still making good profit on PS2, a small profit from PSP (miniscule from hardware and small from software) but are making such losses with the PS3 as to cancel it all out.
last quarter i think the Playstation division of Sony lost about the same amount of money Nintendo made....i will try to find the financials.
There is a reason Nintendo passed Sony as one of the largest Japanese companies (this includes all of Sony not just gaming) a while back, and now has twice the market capitalisation that Sony has (i have no idea what that means but it generally shows a companies worth)
And about the losses per PS3 console: People have just made estimates based on component values to figure out how much Sony loses per PS3, but those estimates usually don't include marketing/advertising, pack-in games (motorstorm/resistance) nor packaging or shipping costs....and probably not any taxes they have to pay in various regions (mainly PAL)
