I didn't get quite that far in my Berserk marathon rerun yet, but it seems he does know the outline at least of what happened, depending on how detailed the description Guts gave him was.
That said, I'm sure he'd sooner or later come in contact with Casca after Griffith brings her to Falconia, but we can only guess how things would go from there on.
The reason Rickert slapped Griffith in the first place is because he knows what happened during the Eclipse. And he's not in Falconia anymore, if you'll recall. But yes, Miura clearly intended for him to meet Guts and Casca again in the future.
Not sure if this has been discussed yet, but do you think management at Young Animal made a stipulation here, Berserk can continue but the releases need to be frequent. I mean, someone has to have sales on their mind, right? Without Miura, that must have been an easier topic to broach with Mori at the helm. Just wondering. Aside from the obvious contributing factor, that may also be playing into the quality we're seeing here.
It's possible, yeah. It could also be more of a tacit understanding than something written in a contract. Either way, I think it goes without saying that all parties involved intend for the project to progress at the best speed it can while meeting a minimum quality bar. Miura was not just Young Animal's but
Hakusensha's star mangaka, so he did whatever he wanted, but other than him and maybe a few others, authors do have to work within the constraints they're given by the editors.
That aside, Miura could afford to take more time because he was also working on other projects, some public and some not. And it was compounded by the fact he had switched mediums, was getting on in age, and was intransigeant on quality. But even then, he seemed aware that he would have to pick up the pace eventually. All of this to say that I believe it's a natural expectation for this project that it will have frequent releases.
In my opinion it would be nonsensical for it to only have four episodes a year (for example), considering they're just conveying what they know of the author's broad intent for the story. It's really not quite the same as creating your own thing. But do note that they're taking a month between releases at the moment, which isn't "as fast as possible" for Young Animal.
As for the financial aspect, I mean let's not kid ourselves, it's definitely a factor. That being said, I don't think that's necessarily the key reason for the release schedule, nor do I believe the frequency explains the quality problems of the continuation. In theory, Mori and the staff have had over six months to work on the episodes we've seen so far, and I'm pretty sure they'd at least finished the first three before the announcement. I don't think spending more time on them would have helped all that much. Miura's genius isn't something you can replace with mere effort.
