They're clearing hinting at something more coming from the Empire. A lot of the "threads" in HW got not very satisfactory finishes too. The Warriors of Darkness, all the random "oh hey we set it up where it'll be this huge adventure to find all of our missing companions from the end of 2.55...but random Soandso saw them here and poof, reunited". The Dragonsong War stuff was all great. I can see where we did kind of "win" too much...but honestly I didn't want the liberation stuff dragged out as my story patches, I want more from the main story as far as real threats go. Empire, Ascians. Give me more of that.
