I would not read too much into WW shooting Mia down. In the last stream he answered a question about Mia with "we'll see, maybe", no longer the certain no, game moved past her. In that same stream he also said not to take things he says on stream very seriously because he constantly forgets stuff, changes his mind, or even lies sometimes. And he said that 1.0 will retroactively add some content to earlier parts of the game like sex scenes, as well as re-work the corruption system, etc. In fact he is considering forcing people to start new saves in 1.0 because continuing with an existing save would mean missing a bunch of content. So all those bits together kind of sound like Mia is not done after all.
