I question how they will deliver it, my understanding is that no current cable box is capable of transmitting true 4k signal because of the need for HDCP 2.1 or whatever the newest encryption is. That's why so many tv's sold that claim 4k compatibility may not work for movies later, because they didn't come with appropriate HDCP versions or HDMI versions for the higher speed.
