Considering they finished the last day event with mostly everyone on the last day at the camp, I believe the next update will add more sprites, probably for Kyouji and maybe someone else, and add their routes there. That could take the same time as before, between 2 or 3 months? Who knows. As far as I know, they have other VN's to work with and this one is the only one they cant charge money to produce. So I doubt we'll have a finished route by the next update.
