Dunno if it was mentioned in here before since I don't keep up with the thread, but when his Patreon got nuked, he posted a link on his Subscribestar to a (close to a one year old) machine translated post. In it, he just mentioned that he works one week per month on the new MG, the other three weeks on the RPG, and that he doesn't post anything because he's a perfectionist and doesn't wanna spoil things. I imagine he's just busy agonising over which specific Japanese jerk off sound effect he should give each monster to perfectly characterise the texture of their handjobs or some shit like that. Whether you want to believe that three weeks per month dedicated to the RPG thing is up to you.
