So basically, they plan to lose over one billion dollars on this. What does that mean? I'm not entirely sure, but as I've said before, I believe MS dis start to make a profit on these things at some point in the past year.
If we assume that the majority of broken consoles were premium ($400) versions, that 11 billion of the consoles have been shipped, that the cheapest way to fix the console is to replace them, and that the exact cost of replacing one is the cost of sale, we'll see that about 23% of 360s were defective.
However, honestly, I think the cost to fix should be less than $400, which would mean that an even higher percentage is messed up.
I would hate to be an MS shareholder right now. They just threw out a billion dollars more on the 360, and will face absolutely no gains from this money.
