As of the July 9, 2024 patch there are 2 additional hot zone levels, 100 and 105.
So far the level 100 one shows up as Shard's Landing and the 105 was Tower of Rot.
A level 125 group got 13 AA, 250 plat and a varied amount of experience.
However the armor drops are bugged and have no stats. No eta on fix per dev
