Sony has lost over $3 billion on the PS3

Sony lost money on the PS1, PS2, and PS3...but made billions on games, accessories, etc......

any idea how much those cost to develop and how much they lost?

I'm curious.

The numbers I've seen for the PS3 are really high - not sure how "real" those numbers are though. Just wondering how it would fit, comparatively, with the earlier ones.
