He may have been talking about the top-end technology, rather than what's commonly adopted. I doubt TV's will go beyond 1080p @ 60 Hz for many years though. 4k x 2k only really makes sense for movies, and > 60 Hz is highly improbable as that gives smooth animation already. There's no need for faster. You're just guzzling up storage for no benefit. Perhaps movies would want to be at higher refreshes to elliminate judder on huge screens, but they haven't yet even got beyond 24 fps! Most games aren't hitting 60 fps. TV broadcasts faster than 60 fps would require stupid BW above the already stupid demands of 1080p60. Who wants to compress the image quality lower to get faster framerates when 60 fps is plenty fast enough? Compression artefacts would look far worse.
The next gen consoles should be aiming for 1080p60, constant, and using rendering power to add image quality.
