Might want to temper the expectation. I am pretty sure in one of the dev's recent replies on twitter, he insinuated it would take until next year. Considering he still has uncleared bullet points in the backlog and it not even accounting the testing phase yet, I'd say that is a fair assessment. Please be a little more careful with how you word it because there might be some people who look at what you write and ask the developer if the game could be released soon, and I cannot imagine it would not annoy him eventually if he is not already troubled by the constant asks.
Sorry if I came off as spreading false rumors. I was actually basing that thought process on the most recent update he gave out. In the later portions of the post (I used google translate)
Dev: So when the game is released, there
may be a little bit of "that still is missing!" and "that system is missing!"
It's easy to add more after completion, so I'd be happy if you could gently expect
that "that element will be added in an update" for things that are n't there
. Fluffy, fluffy."
Pretty sure Dev implied "I can add this system in a future update, whilst releasing the game".
Hopefully the infamous google MTL gave an accurate form of those words. I'm not completely certain, but that may have happened with Summer Memories and it's DLC. Perhaps what they wanted to add is what you mentioned, the unclear bulletins. But may save it after release day.
