You guys also have to take into consideration that it's been two years since they started working on this game. Their Patreon is currently sitting at over 9000 (no pun intended), which, when divided among their small team, gives each of them a pretty penny. They are all probably used to a certain quality of life by now and a certain budget per month. If I were them I would probably also try and drag this game out for as long as possible, thus insuring that I have a steady income each month. I know that sounds manipulative and all, and I agree, but put yourselves in their shoes and think about what you would do. Imagine that you get a few thousand bucks a month for something. You would definitely try and keep doing that thing for as long as you can.
My guess is that they have no idea what to do after this game. Or even if they do, they have no way of knowing if their new game will be as popular as this one and how many petreons they would lose. Both cases would most certainly hurt them financially.
Unfortunately for us, finishing this game as soon as they can is not in their best interest, thus the updates will probably keep being small, even with the new release schedule. My guess is that we'll keep getting new characters until it becomes really unreasonable or they simply run out of them. Then, they will slowly begin finishing the work on each character individually etc. I see this game taking another couple of years to get finished or at least getting close to being finished.
Now, if they could publish this game on Steam, that might have made things different. However, they don't have rights to these characters so they'll have to remain on Patreon.
