I think I disagree with this somewhat. I do think that it will be sooner rather than later. However, with what he has said he has or had plans for, sex for the end of Chapt2 completely makes sense.If DMD had not been banned from Patreon, I would have bet D would have still been a virgin at the end of Chapter 2. A few twists, turns, and cliffhangers would have sufficed.
But as things are at present, fans just don't know. For instance : how much support would Melody have without many patrons making it crystal clear their pledge is to indirectly support DMD?
As I've already stated, the DMD 0.18 update content AND the Melody pledging arrangement are VERY closely connected.
I actually prefer the drama surrounding Patreon and DMD to the game itself. We haven't reached short strokes yet!
I've always felt that with the multi-paths opening up, in terms of bdsm, 3somes, etc... the final chapter would be more reserved for that than for vanilla sex with D.
