yeah that's why Nintendo has to make money on the hardware, the only way Sony does well if there is alterior ways of making money, so the blu-ray in alot of ways was important to Sony. It was no longer just a source of revenue but it was ensuring the success of the rest of the company's endeavors. That's the only reason to take such a loss. microsoft too, they knew that x-box was simply going to lose them money, that was their ticket into the living room which they felt was the future, so they felt like having a stake in it was worth it.
