Think about what's coming, they are skipping ATSC 2 (XML, Blu-ray codec, XTV with interactive Java and Javascript commercials) for ATSC 3 (HTML5, HEVC UHD Blu-ray codec with XTV interactive commercials);
ATSC 3, UHD Blu-ray with Digital bridge and Vidipath in home media sharing
For the most part ATSC 3 (4K TV) will be about 4 times as many channels/6mhz RF band displaying 720P and 1080P and XTV as well as Cell Phones supporting ATSC 3, It's not about 4K programming. Every cell phone mandated by the FCC to support ATSC 3 (4K antenna TV) and many more channels as well as the delivery mechanism supporting: smaller antennas because of multiple synchronized cell Phone like towers for TV, Robust reception in moving vehicles and inside buildings as well as being able to watch a program in a car across multiple TV stations for hundreds of miles on a given TV Network. This is a game changer for broadcast TV and I can see what are now traditional Cable TV stations moving to Antenna TV.
There is a need for a cheap 4K to 1080P Media Hub which we thought was going to be a XBOX 361 or 22nm PS3 (supporting ATSC 2). It's looking like those are not coming so a PS4 needs to fill that role. I'd speculate a PS4 @ $249 and a PS4.5 at $499 sometime around 2018 when Korea plans to support the Olympics with 4K Antenna TV. (XB1 and PS4 confirmed to support 4K media and XB1 confirmed supporting UHD Blu-ray which implies the PS4 can also. An examination of the UHD Blu-ray drive requirements support only a firmware update needed to 2013 drives).
All cable cutters and most Cable TV customers will have a small Antenna for ATSC 3 by 2020. By about the end of 2016 middle of 2017, Combo ATSC 1&3 Network tuners will be available.
