I don't know. I have been waiting until a Female Science Android is released because it fit with the backstory that my main character has had since the game opened. I hope it is Medical-type, but if not I can always teach it the skills to fit the character.
obviously its not that simple. plus its not like this is theo nly thing they are working on. more than likely its a lower priority work that can be put off while the people who can make it happen are working on more important stuff, and when they got the time, they work on it.
we got one already, so its something at least. they never siad WHEN they will have that change implemented.
