ummmm. No. Microsoft is doing great. Nintendo and Sony are hemorrhaging money...
Right now, as in today, yes. However, overall the PS3 and 360 have resulted in billions of dollars in losses for Microsoft and Sony while Nintendo has earned billions. The relatively small profits that Microsoft is pulling in now does not offset the billions lost in the first few years of the 360's life. They will never break even or come close to breaking even, nor did Microsoft expect to break even.
It's not a healthy industry.
