I've said it before, don't hold your breath for 4K OTA. Just because somebody demoed it doesn't mean it will go live. First, if broadcasters won't opt in to full 1080 HD but rather save bandwidth with 720 what makes anyone think they're now going to jump on the 4K bandwagon? Ain't gonna happen. Second, the purpose of 3.0 is to compress bandwidth (repack), 4K OTA expands bandwidth, so which one do you think wins out? Yes, 3.0 could provide 4K and 5.1 audio but that is not why it's being implemented. Bottom line, it's being implemented to facilitate the repack, pure and simple, so put away your pipe dreams. Oh, yeah, one more thing, ESPN doing 4K is irrelevant, they are not a broadcaster, they are cable/satellite bound.
