probably not during Index since I think the recent culling was taken with the index in mind.
If we going by 40K, I expect they will purge any outdated model when each battletome comes out. (Example Badrukk got removed from the OrK codex). After the Skaven, Ogors are the last range to have a lot of resin models, so something (good or bad) will most likely happen then during this edition. There are a few resin minis like Fluxmaster, Epidemius, blue scribe, khorne herad on Juggernaut, and vice leader that maybe gone or replaced.
