Correction: I wasn't able to find a public document that mentions work on
incorporating 1080.60p into A/53, and I believe that it couldn't be done
using MPEG-2 codecs within 18-and-change mb/seconds. (Have to reserve
bandwidth for audio, PSI/PSIP and over-runs.)

I think that the ITU is actually something of a laggard on this, in the
sense that the ATSC has already announced work on incorporating
1080x1920x60p into A/53.
Main Profile@ Main Level (MP@ML) and Main Profile at High Level (MP@HL) are
existing combinations. The former is sometimes called "EDTV" (by some) and
the latter is called "HDTV". Maximum permissible bit rates (per 13818-1)
are classified by profile and level. Nothing new is contained in this
paragraph.
John Willkie, who is "fairly certain" that he has read about the A/53 work
program in a public document detailing future ATSC work plans.
