In the word of Steve Jobs..."Nope"
You can put the drive in the bay, but if you want to run it under OS-X, then the answer is "nope". You can try Boot-Camp and run Windows, and that would work. But if you're going to do that, spend a third of what you would on the Mac Pro and buy an i7 Windows computer with the 8 gigs of RAM, a kicking graphics card, and the BluRay burner built-in and fully supported.
wait, I need some help understanding all of this:
For my (hopeful because maybe Job's will kill this too) future MacPro, can't I just buy a Blueray burner and put it in the second bay?
What about us pro users who shoot in HD and want to burn a comp out to show a client on an HD tv? I thought the newest version of compressor had a setting for BD??
