So far, I have only played one route. I've actually been waiting for the route selection chapter (so, the one we're now waiting for!) to play all other routes that I'm interested in. That being said, I have replayed that route so many times I can't even count anymore. I tend to replay this game like once a week at the very least. But keep in mind I did discover it like 4 months ago, so this is the first time I'm waiting for an episode.
I'm not replaying right now though, since it's always better to play from scratch when a game updates to avoid bugs and so on. It'll soon be 7am so I really have to go to sleep. Hopefully, the chapter will be released when I wake up. I'll only replay chapters 1 to 4 then, with the new built. Considering I wait till night to play so I can be alone and truly enjoy the new content, it'll be cool to be able to replay the old content during the day so I won't get TOO antsy.
