Ok. Im curious about this so here goes some math effort and research findings based on a dirty quick look.

season 1 = 24 episodes = 90 chapters = 3.75 chapters/episode.
season 2 = 24 episodes = 84 chapters = 3.5 chapters/episode.

Less chapters adapted in S2, indicating that they slowed down the pacing of the adaptions.
Although for all we know each chapter might have more pages in s2 than s1, so this seems to be inconclusive evidence.
But it seems to support the general feel that the pacing has slowed down somewhat.

Source material is as of this published post, 258 chapters.

Chapters that has yet to be adapted appears to then be:
258 - 174 = 84

If we presume season 3 maintains the adaption pace of season 2, we just got enough material for a full 24 ep season 3.
If we presume pacing will pick up like season 1, we are 6 chapters away from a full season adaptation.

I think it is fairly safe to say that there will at least be a season 3, so binge watchers might want to hold on for a while longer.
According to a post from dailyresearchplot.com from 2 weeks ago, there is a pretty good speculation on release announcement to be somewhere this summer, and release date late 2021 or early 2022. Presuming everything works smoothly in the production line, which it might not due to this human malware pandemic we are currently dealing with.

If they keep publishing so we have more than 90 chapters, there is a possibility for a season 4. As of this post, the manga is still getting new chapters published.

But if @coolxal is correct and the manga is ending soon (but after 90 chapters), OVA/movie ending becomes a possibility as a replacement for season 4.
