Final Fantasy 14 was full of people as Dark Knights holding vigil the last couple days, and Bards using the 'perform' action to play Guts' Theme, as the player community of 14 is, if nothing else, good at that kind of stuff.
I read on Reddit that he had story-boarded the rest of the story and that he had strong control over the IP, so there is hope that there will be a coherent ending to the story. I'm sure there will always be the question of 'Is this how Miura would have wanted it', but at least there's something.
We've lost a pillar of both manga and grimdark, I feel sad we'll probably never know the end of that masterpiece. Even if others step up, it'll not be the same, and unless he told them of the storyboard for the rest of the story, it'll feel like desecration to continue...
@Boomfly: The saddest part is that this is not an isolated outlying case, but the norm amongst mangaka. It's an industry that makes video game companies and their crunches look positively lax and benign in comparison.
I never got into Berserk but I feel everyone's pain at the news of this loss. This makes me worried about other mangaka that don't take care of themselves and push themselves to pen 12 hour days. It also makes me think critically of Oda for seemingly refusing to end OnePiece. No one lives forever
From his own statements: he hadn't had two days off in a row for years and slept 4 hours a day. There's no inborn 'talent', he sacrificed his body and mind for the sake of his art. Draw for ~18h a day for 19 years, you'll be as good as him. (Hiatuses started after 19 years.)
