There's no word on how much it will cost, but the box will be available in late November. NHK did some test runs of the technology in during the Rio Olympics in 2016, but this is just another step before any big commercial technology is released. Since TVs supporting newer standards like HDMI 2.1 aren't out yet (and the spec wasn't ready when those 8K TVs went on sale almost two years ago) plugging the box in for viewing will require four HDMI cables and a software update for the LC-70X500 Aquos 8K TV.
