I know the LNs are massively popular in Japan. It's just that people are talking about how it might not be profitable for JC staff to have the anime considering they are the third name down on the credits for who is associated with the production, and especially because the studio might not need the anime third season yet to increase how many light novels are sold from the first series.

I feel like the manga catching up with the anime will give them sort of an incentive to do it, and especially the fact that the new NT volume 9 has been so massively popular to people reading it. I think it'll be announced eventually, just not yet. I'm personally hoping it gets announced this February also because by then, most of Railgun S releases will have come out by then, and the movie will have already been streamed on tv for the final time, so they'd have no reason not to announce it if they thought it was profitable. I'm just worried about whether or not they think it's profitable enough.

At the end of the Index-tan for the movie they were talking about how this might just be the peak of the series' popularity at least for the anime. Though, I'm still hoping of course it'll come out. I just don't know if now is the right time; though I hope that what happened with FMP doesn't happen with Index.
