Can your PS3 burn Blu-ray discs and edit HD video?
Blu-ray isn't the only HD video source. You're thinking about producing Blu-ray discs using a Mac. I fail to see how this has any link with a Blu-ray drive in a Mac Mini or iMac as you won't be editing HD video on those either, only playing back movies or using BD-Rs for data storage.
The BD-R part is covered by 3rd parties, the movie play back by my PS3. If it was such a killer feature, it would impact sales.
Again, are you sure it's not that you want Blu-ray support and are trying to pass it off as a "must have" feature ?
Not everybody, but some. Does everybody need to want something for Apple to deign to at least provide the option for it ? Some of the computers I sell have it for the price of a Macbook for heaven's sake.
Seeing how Blu-ray is licensed and will require some product developpement, I'm guessing that before Apple provides Blu-ray options, maybe not everyone will need to want it, but there will need to be enough demand as to cover the costs associated with implementing and selling the technology.
They aren't going to lose money over a feature that some want.
