Just a small rumored bit that Sisters of Battle..... well Adeptas Sororitas are already in production. That doesn't really give us a timeline, but it does hopefully mean its sometime this year, and with new models.
I spent a little time trying to find out additional information, as the bit below was posted in the comment section a few days back by Randy. I could not find out anything additional that could be shared, but in the past Randy has had small bits like this before.

They are already in production and mostly done.
