Samsung told me March for their Ultra HD BD player.
Panasonic was the only other company announcing a UHD BD player for US distribution. I have a meeting with Panasonic tomorrow and I'll get more details and hopefully price and release date.
Here's a photo from the press conference today that is on my site.
Sony Consumer Electronics announced today that Sony Pictures 4K HDR movies can be downloaded on all 2016 Sony Bravia 4K TVs.
