Uh, they better get LG to play nice and resolve that patent dispute. You have some of the best looking OLED TV's on the market that could be more than capable of ATSC 3.0, but software locked to ATSC 1.0 due to patent issues.
Then they have to figure out the DRM issues. HD Home Run users can't easily distribute ATSC 3.0 through the home with Plex or many other playback devices and software. The DRM basically kills it.
ATSC 3.0 may have some nice features, better reception, more efficient codecs - but there are definitely major setbacks.
