Of course, it's not actually time to throw your 4K (or if you're really old-school, 1080p) HDTV aside. Ultra HD Blu-ray movies in 4K are still just around the corner, and actually delivering 8K video is still a few years away. Testing out broadcasts is one thing professionals can actually do with this new display, and Japan's NHK has been working on the technology for years. Public tests could start as early as next year, and the first broadcasts are scheduled for 2018. I saw a test 8K broadcast in Washington DC during the 2012 Olympics, and while it was amazing and immediately well-beyond anything else I've ever seen before, it required nearly an entire room of equipment and a connection via Internet2 just to handle all the data. It will probably be 2020, at least, before 8K is any kind of realistic option, so don't worry about future proofing just yet.
