The problem with 4K availability is that content providers have put so much effort into preventing leaks by strangling their content with tons of DRM. That means, HDCP requirements, absolutely no playing content on a PC, etc. It'll be years before you see any kind of UHD via cable. Not to mention consumer internet providers provide horrible service across the US which can't even support the bandwidth needed for those streams.
