Awesome. Yet another way they want to screw us. While this might sound smexy-smexy to some, I don't see any upsides for consumers. We'd have to replace massive amounts of existing equipment, worry about the fragility of the new connectors and it's another opportunity for the music industry to lock down an interface with DRM.
I have a significant investment in music production equipment and ham radio equipment (both purchased and home-built). Having to worry about availability of something as simple as a set of headphones or how I'm going to get an analog signal between two points is utter BS.
Evidently, they want to keep content locked down so tightly, it will make things painful for the customer. Why not just force everyone to get a brain implant so they can bill us if one of their songs is stuck in our head?
They already screwed us over with everything else, why not this too?
