Sony's action cam HDR Exmor back illuminated sensor is hitting the open market now after serious production hiccups for all forms of sensor due to earthquake damage at the fab plant. These problems were confirmed at the giant Photokina show in Germany last month.
If you are not in a rush you at least have the time to go and see the TV sets. Even the streaming companies are sold on it when most of the TV companies just went 'Meh" for things like 3d.
Its one of those, 'You've got to see it things.' I do pity the poor sods who have to market HDR on traditional media though. Seeing is believing will be the key.
All of my cameras also shoot video and and the support industry like Australia's Atomos are fighting to get their magnificent Recorder/Monitors offering HDR at each product level.
