I looked into this recently and estimates ranged from $1 to 10 Billion still to go before breaking even. About $5 billion of the variation seemed to hinge on whether the money invested into the first XBox could just be written off which I personally don't think makes much sense so you could say 6 - 10.<p>The part of Microsoft that makes xbox along with the zine and PC games made a profit of 0.2 Billion this year and 0.5 Billion the year before.
