At this point, it could only be one of two things.
1. The so-called "milking" is intentional.
I've only taken a glance at the dark path. But based on what I've seen. I would not be surprised if he is capable of doing that.
2. It's severe ADHD. In which case we will probably never see the end of it. (speaking from experience) It will become longer and longer between updates until he just won't be able to find/force the "spark" anymore. And that will be the end.
Also, if this is the case the "nagging" from fans, could contribute to making things worse.
So for your own sanity ppl. Stop building hope. Just walk away. And, instead be pleasantly surprised when and if a new update drops.
