NHK and MLB joined forces Friday night for the first-ever telecast of a major league game in 8K Super Hi-Vision, the latest technological enhancement to our sports-viewing pleasure.

It probably will not be until around 2020 - in time for the Tokyo Olympics - that the Japanese company's new-look TV picture will be widely available.

The promotional material said 8K offers 33 million pixels, 16 times that of HDTV (2K). So, what's next after that? Nothing, according to Hiroyuki Nishizawa, executive chief engineer for NHK CosmoMedia America.

"My personal understanding is that 8K qualities of resolution is the ultimate number for humans," he said. "We have a limitation of what we can notice. This is the final for picture quality."
