Hello there,
pregnancy will be a thing in future updates BUT it won't be a full system, more like a series of events. Evelyn already has this kind of content. As for the endings, those are placeholders and will be reworked in either 1.9 or 2.0.
There are 3 futas with some scenes in a cast of over 40 characters, it seems like a lot of futa content because they have arrived together but in comparison to the number of scenes in general, is a really small portion, however, that should be it for the futa characters. there are no plans for other futa characters at the moment.
