$350,000,000 a year and climbing.

But console makers are supposed to make about $10 on each game sold, and the XBox game sale ratio is about 5:1, so they might make about $50 a unit on the software.
So that averages them out to losing maybe $50 (American, of course) on each XBox. Meaning $400 million in losses on the XBox so far. But that $350 million figure above was for just
this year. Reportedly Microsoft is hiding other money losses inside the XBox's department. The rumor is that they're making big cash payouts to help keep a secret "well known major Japanese developer" (most likely Sega) afloat.
