If you are a fan of the Amazon ecosystem, you can now place pre-orders for brand new Elements 4K HDTVs with Fire TV built-in (aka Fire TV editions) in 43, 50, 55, and 65 inch sizes, with prices ranging from $450 to $900. Many of them also have a bundle with a free HDTV antenna. The Sound Bar bundles go for more. The shipping estimate is mid-June 2017. Detailed pictures of the TV and remove further down the product pages.
Of photography interest, FireTV has a handful of photo-related apps, including Smugmug, VLC, and a variety of gateway apps by 3rd-parties that offer access to Flickr, Google Photos, OneDrive, file managers, along other mirror/casting apps.
