AV1 seems to be the future of digital online video, but you could just as easily run a service of channels in HD given the amount of free space given from this codec. Could Freeview adapt to this format? Time will tell with DVB-I in planning at the moment.Judging by how we're still broadcasting in MPEG2 for SD channels, I don't see AV1 taking over on Freeview any time soon.
AV1 is still making its way out there on Desktop platforms (with only the latest CPUs/GPUs from Intel, AMD and Nvidia supporting AV1 encode and decode) - imagine how long it will take for it to trickle down to budget TVs.
The next step for TV is probably the closure of DVB-S and T mutliplexes and replacing them with DVB-S2 and T2 multiplexes, along with switching to the more efficient H.264 (AVC) codec to give us more breathing room. Again though, this all comes down to cost.
