I don't know if we'll get it with the sanctuary elves or the girls at Kali's university, or even with Kate or Moon. Right now, we have those events for the side girls, but like you. I would love to take Nia, Moon or Vanessa (or any of them to be honest) out on something like that.
I don't know what Runey has planned for the side girls, but the dates is a good step towards learning more about them, brings the player closer to the girls. The dates are a good addition, even if it took away from character advancement and story progression.
I'd rather have the story vs. the sex anyway, and I'm that way with all of my VNs I play.
