Nope. I remember reading an article at Light Reading a few years back where one of Comcast's top guys said that the only way they would ever transmit 4K would be via IPTV. Didn't make sense to devote the bandwidth necessary for 4K QAM channels. A lot of folks don't realize the degree to which Comcast has already shifted toward IPTV. In many areas (including here) for over two years now new customers signing up for both broadband and TV service will often, by default, get the latter provisioned to them exclusively via IPTV using a new generation of IP-only X1 set-top boxes that record only to cloud DVR. They're basically just streaming devices. (You're also given an option to just use their Xfinity Stream app on your own Roku, Fire TV, etc.) The older generation of X1 boxes (which still constitute the majority in use) are actually hybrid and can do both QAM (i.e. they include actual tuners) and IPTV, with internal hard drives for DVR. But even on those, there's a handful of channels that are IP-only (and are therefore completely unavailable to pre-X1 QAM STBs and TiVos). And even if you have a physical X1 DVR, you have cloud DVR too, with your local recordings getting mirrored to the cloud so that they're accessible on other X1 boxes and via the Xfinity Stream app. Comcast is basically in a years-long slow evolution away from QAM to IPTV. At some point, who knows when, they'll just shut down QAM and reclaim that bandwidth for broadband. I think that will have additional network benefits too, in terms of simplifying the architecture.
