I think we'll get a similar Higurashi ending.
Again, as I said before, Featherine is most likely the first 'magical human', similar to Hanyuu in Higurashi (dohohohoho) because it's more that Hachijou comes from Featherine, rather than the opposite. I do believe in parallel worlds and magic, in some form, has to exist for the game itself to even exist.
