You don't really need native OSX support for BD movie playback to do what we are trying to do here.. which is ripping / encoding. It already has all the support it needs for raw access to BD drives. Native BD movie playback is a different problem to solve..
I'm just saying more devs will start to develop ripping apps on the mac side once it's supported natively. Right now, this is the only one that you can use on a mac. I'd say we will see a few as soon as bluray support is added, maybe even an anydvdhd port to the mac side..
