No actual details have been released yet. However, as previously noted, if uncompressed 4K equates to 500GB per one hour of content, then even at a compressed rate it doesn't seem (on the face of it) to be worth it to record 4K at this point, as you'll have to have a significant portion of your DVR reserved for one show, and maybe not even an entire show.
We'll see.
