Re: Both Sony and MSFT lose money on the hardware
Unless you have concrete information about margins and hardware costs, his info is as good as yours.
Malfunctioning devices, inventory shrink (theft, misplacement) are always factored into the release, as 10-15% (due to the high profile of this item, closer to 20%) of the stock is expected to be lost or returned (with credit issued to retailers who beat those odds in a significant amount). Any retail manufacturer knows this before contracting out for retail stores to push their product.
