Dark Cookie has said before in his streams that he's not against the idea, but he needs the game to be a lot closer to completion to even consider it. He's also said that if and when he does, that he'd try and have the game be as cheap as possible, seeing that it'll already be paid for.
I really don't know about the future of h-games, but I know that AVNs are in a good place.
Most sandbox games were always kinda meh, to be honest. Since they come with a certain grind aspect. Even Summertime Saga was supposed to have it, what with the stat increase and all. They don't really respect the player's time and that's the huge failing. Meanwhile actual VNs might not have much game going, but you can always play at your own pace and the dev might even put focus on something like plot! Shocking, right?
