I think Sony is more looking on the long term marketing
Which some report also show although blu-ray is not popular now, but there is a increasing trend
Just look at why sony use blu ray on Ps3, why don't like 360 using DVD, which is also much more cheaper.
I amit that sony make a mistake that the high price of PS3 is a loss, that is why they now move away the BC and making a cheaper but still high quality console.
