This is an old article 1/6/13 concerning CES show. I think it sheds some light on the subject, and maybe awesome possibilities. If this has already been hashed out forgive my ignorance. I omitted some of the article but provided link. My main thought is concerning the second and third highlighted paragraphs "no broadcasters have concrete plans..." EXCEPT FOR NANOTECH!

Also the last paragraph concerning Japanese broadcaster takes 4K to the next level I think 8K.

LAS VEGAS -- Samsung Electronics is unveiling here today two ultrathin TVs and a prototype LCD TV with four times the definition of today's most advanced high-definition sets.

Samsung previously demonstrated its 14-inch OLED prototype last year but the 31-inch is new. It's also the largest OLED TV panel yet shown by a TV maker so promises to be a star of the International Consumer Electronics Show.

At the show Samsung will also unveil a prototype LCD TV that boasts a resolution of 3,840 pixels by 2,160 pixels -- that's double the vertical and horizontal resolution of a current "Full HD" TV set.

The display is therefore expected to offer a crisper, clearer picture than is possible with today's TVs but could take a while to be commercialized because no broadcasters have concrete plans to launch higher resolution services.

Japan's public broadcaster, NHK , is one of a number of organizations researching next-generation HDTV and has demonstrated many times a "Super Hi-Vision" service that offers an even higher resolution than the Samsung prototype TV. The service has 7,680 pixels by 4,320 pixels and isn't expected to launch commercially until sometime in the next decade.
