Yeah, these are all really good points / predictions. I think WSJ's game plan in 2021 will involve two main angles:
- Establishing a new hit in 2020
- Giving a 2018 or 2019 manga a boost with an anime adaptation
The first angle is obviously pretty hard to predict the specifics of right now. But it's interesting to think about which current series might land an adaptation, since there haven't really been any debuts lately that are Neverland tier. Shueisha will likely still want to throw out some new anime alongside what's running currently, even if it's something that's kind of middle tier, in hopes of the adaptation boosting it to true success status.
With that in mind, these seem like the current best candidates for a 2021 (or maybe late 2020) anime adaptation:
- Act-Age
- Jujutsu Kaisen
- Chainsaw Man
and maybe Samurai 8, if it succeeds over the next year. Act-Age and Chainsaw Man in particular are very weird, experimental projects so adaptations of them would be interesting, to say the least.
