Let me address some other points you 4K-naysayers love to bring up.
Consumer demand lacking. Yes, it will take years (a decade?) for 4k to gain a majority market share, but
this all tech is getting cheaper and faster everyday. 4k LCDs are barely more expensive to build than 1080 which is why almost all 2015 TVs are 4k. LCD panels are not expensive in 4k. There's simply not much reason for manufacturers to make a 1080p TV when 4k is "right there" in price. You're going to get 4k soon when buying a TV, it's simple. The differences in local dimming, and things like SUHD are what makes the difference for LCD prices/quality, but they don't restrict access to 4k and you can still get a big set with the needed resolution for rather cheap. 4k is waaayyyy cheaper at this point in the life-cycle than the 1080 panel roll-out was.
Compression technology is getting better and HEVC standard will improve
any video stream bandwidth when it can be adopted (this is the real difficulty and the internet has a huge advantage with this). We don't need to think that 4k is going to take 4x the bandwidth to provide a channel. Many TV channels
will need to wait a long time to have 4k content to distribute. We're not talking the Top 120 package going 4k in 2016 (4k Law & Order re-runs!!!). Almost EVERYTHING being recorded
right now is in 4k. One reason for this is the options it gives in post-process, but also the future proofing of the material. Movies and major live sports are always filmed/recorded with 4k cameras, we just don't have access or distribution methods for this content yet. Those hit this winter. (Remember you can probably even record 4k video on your phone's camera right now, but you probably need YouTube do distribute/view it on another device. Think of how long it took 1080 to be recordable on a consumer product, not to mention
your phone.)
We all know Dish has some crappy compression now, and there's many wants like, full-time RSNs (or even CSNNE). But there's nothing that states that Dish needs these 4K channels/content full-time. They could be provided via the internet to your 4k Joey directly or partime time much like RSNs run. Stations will still have a glut of HD content. In 2016 if satellite can simply provide whatever "big game" or "big event" (Walking Dead?) is on TV that night in 4k, most of us will be happy. 4k is going to be great for live events and you'll maybe need 3 concurrent 4k broadcasts to satisfy most of the public in 2016. Movies are obviously the second best thing for 4k, but VOD can take care of this and would provide you a better picture than whatever Dish would compress a 4k movie network into anyway. Not counting UHD Blu-ray's, there will be many alternatives way to watch 4k movies in 2016. Vudu, Netflix, Amazon already offer this, and once movies are regularly released in UHD (look at the first batch available on VUDU this month) this will be a hard area to compete in with dish. VOD is actually the more attractive option here. Satellite will still want to compete in movies, but it's not a competitive advantage. But, Monday Night Football on ESPN4k?
That is a competitive advantage.
Every (tiny exaggeration) new TV today as a multi-core processor(s) in it that can easily decode and render 4k video. Dish and Direct will not want people relying on their televisions built in tech to get content, or they will want to be involved with their own app. Sat providers don't need consumers getting used to Netflix and Amazon anymore than they already are. Likewise, content creators that don't sell much to these services (LIVE SPORTS!) will want to make live 4k as big a deal as possible when it roles out. Look for networks and Sat to team-up big time in the push for 4k. It helps them both.
Don't be cable Rob Lowe, be 4k Rob Lowe.
Lastly, 4k will give dish & direct a huge advantage over cable. Think how long it will take these companies to get their Windows XP era STBs and cable systems upgraded to 4k? Satellite will have a huge market advantage for years.
Can you tell I have a 4k tv
