Just based on what Ive heard in their videos and such, and seen. (IE Frozen Horror in the background) I would expect
there is a good chance if seeing all of the old expansions, plus expansions to go with the new quest books. They have already shown
that they want to do more by introducing the Knight pack. Which I see as a successful experiment, so I would expect to see more like that.
And the Dark Company would be an excellent opportunity to introduce a new bigger style expansion, depending on how they want to do it.
