I think the final piece of the puzzle would be 60 FPS 1080p capture ->
720p delivery -> 1080p display, like my often posted John Watkinson
article sort of suggests. The displays will become cheap, it hides the
pixel/raster structure even at 3 screen heights, and can be done (if you
must ;-) ) with MPEG-2/ATSC just fine.
