From the 1st March 2019 dev stream:
“Just in terms of the story to be perfectly honest I feel like to do the story justice at this point we need to do something much bigger than an expansion. And there’s all this stuff, those of you who are paying attention to the dialogue will know Ulgrim and the Emperor, there’s something going on there, the Emperor’s son, those are all big stories that would really need a lot of dedication to do them justice. And how far you get from the capital would just seem insufficient.”
