Amazon's next Fire TV box: An educated wishlist

Amazon's Fire TV is currently the best streaming box for most people, thanks to its clever interface and powerful voice search features. The current Fire TV only supports 4K video, not 4K HDR like some rival streaming boxes. And if you look across the entire streaming device landscape, we've seen plenty of innovations that would be ripe for Amazon's picking. I've been thinking about what a third-generation Fire TV box might look like ever since AFTVNews reported a couple weeks ago on a rumored mid-tier Fire TV device--possibly a souped-up streaming stick--with 4K HDR support. I can't imagine Amazon would let its flagship streamer fall behind in video resolution, so I suspect a new Fire TV box is also on the way.
