Don't keep your hope up. I honestly feel that the guy will do pretty much the same since he milk them these far might as well keep the same pact cuz moneys ain't gonna grow themselves unless someone pay him up.
As far as I seen his approach of marketing I would he say, he's the guy who extremely greedy and show no sign of remorse or learned, he been crowd funded for years and this the quality you expect to get for the next game (which might as well come out about no less than 3 years later) and sold his game here and there throughout internet when lastly, decide to split up the included content and sell then separately on DLsite(Gun Airi) because he see more way to milk them off then why would he left it there when he can.
From what I been experience, most(assumingly) sold pop on Adult game title were tent to stick to there guns when it already successful on sell rate especially self-made publish so they wouldn't risk or waste their effort on the next project when they expect to be sold pop anyway, still, very few do improve and they reserve more faith within their title but I don't feel this guy is gonna be one of them at all.
Only thing that would prove me wrong is the actual next title that he will release in next couple years to come, until then I would never have my hopes up on him.
