With all due respect I find the argument that claims Xbox360 is profitable baseless. How you can figure that out when others can't is remarkable.
If you happen to have had a good look at MS's ledger and was able to break down the money generated on each product in their entertainment division then I humbly apologize. Else it's just speculation.
I read a recent report from the WS journal that was the exact opposite to these claims but as I can't be bothered to look for a link to this story so I'll just leave it at that.
Everyone that purchases an xbox doesn't sign up to live or buy accessories.
The xbox360 is a superior console to the wii. If Nintendo can sell a souped up 10 yr old gamecube for more money than a hardware superior (and obviously more expensive to produce) x360 and MS still make a profit..wow. Nintendo must be raking it in. Well, they are.
No matter how many billions you have in the bank operating on a loss is frown upon.
I cannot speak for MS as I don't work there neither am I friends with anyone on their board.
I trust they will do what is right, afterall they pay people a lot of money to make these decisons who are far more qualified than I am, but maybe not as qualified as some here.
But that's why we are here, to speculate about such things. Just don't turn speculation into facts.
