Now the diodes etc. are much cheaper, I would say the blu ray drive is economically viable for the next MBP updates, but I have no idea about power consumption or industrial design. Apple has been on the blu ray bandwagon for a long time, the platform has been around for years now, it's won the format war, and frankly DVDs look awful on Macs these days, all of them coming with extremely high res screens. Every single Apple computer is crying out for HD. But is Apple gonna maintain it's astronomical mark up on MBPs and deny us a blu ray drive for a few more years? And make it some hugely expensive upgrade? Whatever happened to year of the HD? The only HD content Apple supplies (bar podcasts) isn't even available on their computers, let alone outside of the United States!
