Re: High end pre/pro's. Are they worth it???
1. As long as your receiver or pre/pro does HDMI 1.1 or better (both video and audio) you can accept PCM for the new codecs.
2. This is still undecided, and is in large part a problem of standardization. Right now we do not know how it will ultimately be done.
3. While their are souces and displays as well as pre/pro's and receivers that can handle deep color, no software is out with it, so until the studio's start selling something with deep color, it is just vaporware.
Hope that helps.
