There are a number of TV Mfg's already supporting h.265, LG being one of them and I think, Samsung is the other, in all there newer 4k TV's.

I'm not aware of any promise that any modelst currently sold support h.265 out of the box. If you see the spec sheet for an LG or Samsung model that asserts this, please advise.

Statements at trade shows seemed to say that LG had plans to sell an h.265 decoder as a "dongle," and that UDTVs with built-in decoders would not be made or sold until the broadcast or streaming industry agreed to implement h.265 for 4k content.  Discussions on that are progressing, but meanwhile it will continue to be chicken-egg: limited demand for 4k displays because of little or expensive 4k content: limited 4k content because of vast bandwidth required by current codecs and non-existence of viewers with h.265 decoders and 4k screens.

Netflix may lead the pack by streaming House of Cards by HEVC / h.265, supposedly at about 15mbps, which would be about the same as XAVC-S at 30mbps.

Darned if I can find information about the vendor or price of the dongle or box adapter that would be required.  How can they stream h.265 without promoting the necessary ad-ons?  White papers and conference statements don't equate to customers.

To encode to h.265 will be very slow, compared to almost real time encoding of some 1080p video in h.264, but perhaps bearable for people who remember encoding to MPEG2 on a 1.8ghz monocore P4 in 2003, or the vast insane trouble some folks take to convert raw DNG to video.

If any affordable cameras capture 4k video in h.265 (perhaps by 2016?), that format may not be any easier to edit than AVCHD was on a monocore PC, except perhas by proxy.  Even then, any content exported from an h.265 project could possibly result in similar or higher IQ loss than if one started with XAVC.  The only way to know will be when someone publishes an h.265 encoder that people can use to render their video to HEVC.  Cyberlink, Apple, or SonyCreative might consider this.  Adobe will follow, if slowly.  If they wait too long, some 17 year-old geek will write a free app and ruin their prospectss to make money seeling HEVC upgrades!
