Too many Romans, need the diadochian armies, more macedonians for Alexander's campaigns, hoplites, more ancient Indians, I think Persians are covered good though but there is a big gap for the Successor states period.

I absolutely agree with with the findings/suggestion about the 2 big 'hole'

Byzantine Empire (large area with a lot of colorful sets)

Successor States (from Macedonia via Egypt and Seleucids to Bactria and e.g. hellenistic City-States with a lot of different sets: infantry, cavalry and - important - war elephants)

These will open complete new collection ranges.

I'm pleased to see that some other people feel that the lack of Byzantines is a big hole and hope that one day it will get filled. Another thought that has occurred to me is the situation with late Romans. Obviously, another manufacturer quite comprehensively covered them but the sizing and quality of the sets is incredibly variable - nice heavy infantry completely dwarfed by medium infantry and really soft detail on many of the other sets. Although I bought that other manufacturer's range, I have not made much progress in painting them and organising them as an army as this variable quality demotivates me. I would love to see Strelets cover the late Romans with a full range of figures of much more consistent size and quality. There could even be a bit of a crossover with mid-period Byzantines.
