So the Berserk movies look like it's going to be a retelling of the Golden Age Arc, which was what the original series was about. However, it will stay truer to the manga. Split into 3 movies, with the first one debuting in Japan in January.
I hope that's just a starting point. I want to see the rest of the Berserk story animated, but I guess, given how different the manga is from the original anime, they couldn't just pick up after the Eclipse. Too many changes would've had to be made. So they had to revisit the Golden Age Arc. Hopefully, once they do that, they continue with the story.
