But then what becomes of 1080i and 720p; they are no longer needed. What a concept? Only one high definition standard.
As far as I know...
Terrestrial broadcasting will likely stay 1080i + 720p. To change all receivers (again) likely will not happen... at least for a few decades.

Cable (and other delivery methods) might move to 1080p50/60, but this will require a compatible set-top box.

My guess is that SD broadcasted digitally will stick around for some time (much like how AM is still around).

2- With AVC compression, 1080p50/60 may deliver slightly better quality at the same bitrates. (I've not seen this for myself.)

3- From a production standpoint, most facilities are wired for 1080i/720p. The higher bandwidth of 1080p60 requires 3gbps cabling.

It would also require VTRs that support that, and other infrastructure (e.g. routers).
