If you check the patreon page, even without being member to see the full post, the title of his lastest update 31th July is titled with "release date", so since another post partially public said it was pretty much done a few month ago and started the editing, this mean the next update is most certainly about to release (for patreon i guess) very soon.
It's also consistent with his yearly release schedule.
Brace yourselves for another tour into the horror of the Harran (°^°)'
