The only thing I forgot was the PS4 R&D. So the losses might be as low as 4.5 - 5.5 billion USD.
Vita might account for another 300 - 500 millions. That's 4 billion - 5 billion!
And it still is a very positive estimation for the PS3.
To prove my point, here is an Interview with Howard Stringer, former CEO of Sony from 2008:
"Q: You have spent three billion dollars on the Playstation 3, disregarding research and development. Can you ever get your money back?
Stringer: Not for as long as I live (laughs)."
