Right, to those who didn't know, the team's next project is essentially "Hentai Darkest Dungeon", once again heavily revolving around pregnancy and childbirth. It's planned that your units can be raped by enemies in battle, and can potentially give birth even during a fight, which can affect your strategy. For instance, a girl might lose her turn if she gives birth during the fight, and after recovering, she'll take a hit to her stats as she needs to concentrate on holding the baby. We know that some status effects include Arousal, Armor Break, Pregnant, Gave Birth, and Holding Child.
Based on early plans, pregnancy will be the main means of resource management, trading the babies your girls deliver as a form of upgrading your units/facilities (very similar to Heirlooms from DD).
The latest blogpost says that they're officially moving to full-scale development on this project, though they'll still put out bugfixes to MBM as needed. They're also putting out a trial sometime soon, so I'm very excited. A Darkest Dungeon styled H-game is right up my alley.
