If you even have the ability within you to deny what an unbelievable comeback story it's been, then you obviously weren't that interested in the industry at the start of the gen; it went from the biggest blunder the industry has ever seen (3D0 and what not are small time ventures in comparison, lets get real) to far and away the most respected console and library of the gen.
Purely as far on the business side, that's a tiny loss compared to what we were expecting just 2 years ago even.
EDIT: Oh, and as others have already pointed out, many of the loss figures you're citing aren't limited to PS3, so in theory it's even possible there is no loss (realistically not even close to the case, just saying you haven't proven a single thing).
