Let's say you can get 20 stops that is useable in post production off of a sensor. How are you going to record it in a way that makes it useable in post production? I can't even imagine the bit rate that be required to capture 30 differentiated stops that would allow for color correction to a normal image in post.
20-30 stops? I don't see any indication that technology is on the horizon, either on the sensor level or on the recording bandwidth level. Sure, I think we would all like to basically stop worrying about getting the right exposure, but that is a long long way off.
Your new features list appears to be correct, but the interface description and video in the 9to5Mac link are about version 10.3.
Based on what I've seen, the four pin connector is from version 1 of these units. Version 2 has the same two pin connector as used on the Teradek and is supposed to have better range. Trigyn probably sent NFS pictures that weren't updated.
With 10% off, that's a good deal. These are the same as the Cinegears Ghost Eye for those who want more information.
