Well, the dev claimed the story/plot would be the same just the all the other stuff that plays the story out will be changed, well most of it. And other visual updates to scenes locations and characters. There were past pics posted to show the changes, their home and one gas station looked different for example.So technically we get new game with different story, with same name and same protagonists (except Miru, which probably be highly melancholic, instead of instant fury). As I usually say "We will see..."
I am hoping for these past 15* (not 18 my mistake earlier) months he was working on it even if most of his time was spent on Summers gone. I am going to assume he at least has the first 2 chapters done and maybe a third and will release them in chunks and not sit on completed chapter to release them one at a time months apart.
Im not too hopeful about miru's visual update and personality change..
