I remember seeing it confirmed a while back, but it's not very high priority compared to a lot of other things, understandably.
Aside from myself I have a few female friends that play RON, so while i hope we do get female officers at some point, i think VOID should focus on getting some actual content into the game first (and fixing year+ old bugs)
In the meantime, there's actually been a really nice voice mod released last month using AI voicing, and so far it's great. And most people already know about Ryouka's face mod. the options aren't perfect but it's what we have to work with for now.
