I think all the season and light novel info has been updated. Season 4 is a ways off, the two Date A Bullet movies were a while ago, the Date A Live Visual Novel trilogy game officially for English came out in 2019 and the next one (which will have Natsumi and another character in it) isn't available in the west yet or even fan translated in videos much either I think and the Light Novels ended. My guess would be minor fixes or small detail edits to certain wiki pages may happen but otherwise my guess is everyone has done everything that is up to date for now. Besides whatever other questions in the forum they have. But I think everyone has talked about a lot of topics so far as you can see below. Or are talking about the series on other social platforms possibly.
