I mean in the sense that it isn't left up to Microsoft. Let me explain. Windows 7 Home Basic can't even play DVD's out of the box, extra software is required. I believe it could be the same for W7 Business and Enterprise, certainly was for Vista anyway. And no versions of Windows come with Blu Ray playback capabilities as standard, built into the OS. It's left to third parties. And obviously Microsoft don't make Blu Ray drives. So why is the pressure on Apple to incorporate Blu Ray? All new Macs support HDCP via Mini DisplayPort or HDMI. Why not pressure third parties into releasing Blu Ray playback software, and attach a drive via USB/FW or internally in the case of the Mac Pro? I can understand the whole "Apple makes the whole package" mantra, but if Apple aren't willing to provide then get someone else to do it. Has anyone released this software yet? If not, if not one single company has, that would suggest there is not enough demand for it. I think people definitely need to realise that MR != All Mac users.
