The PS3 losses have certainly exceeded $6billion.... and are probably nearer $7.5-8billion (the only way to argue against this is to assume that the PSP has lost more instead... I estimate the PSP is somewhere between break even and $1 million profit)
The Wii has certainly exceeded $4 billion as Rol said, I think it is probably about right, between 4 and 5 billion.
The 360 is a bit tougher to estimate, but I would say it's between $1.5 and $2.5 billion loss at the moment, but they are making a profit now so in 18 month - 2 years time I think they will be break even for 360 (though still at a loss with xbox division due to original xbox)
