I just hope that, with the new game, the developer will bite the bullet and introduce more exotic variants of NTR (beast NTR, incest NTR, futa NTR etc.) Summer Sweepers already introduced some of those, so hopefully Impy will go all the way.
Also, I wouldn't mind a romance/relationship going from start to post-wedding in-game, all the while soaked in NTR.
Impy has said they're more into light-hearted NTR and want to avoid too serious a tone in their games, so unfortunately I doubt we'll see anything too hardcore. They're currently making 2 new games, Bastion and Monster Monsoon, alternating development every month.
Someone already shared the kinds of 'antagonists' you can expect to see in Bastion
Alongside the giant futacock centaur, the pit of slimes and the magic illusion crystal already in the game. You also have your fat, asshole brother and strict futa aunty who will be trying to bang you companions
Monster monsoon had a poll for rivals with these:
The futa and the shota ended up winning, but we might see others further down the line and Impy has been talking about adding the 'Sprout Queen' as a final boss who will kidnap your main waifu and seduce them from you, though no set design has been made yet
