WotC just needs to do whatever it takes to allow Weiss and Hickman to write another series of books in the setting (if they even want to at this point). I think a good option would be a new novel series and some accompanying dragon articles with some class features, feats or mechanics...
....however, they are itching to take on the Daggerburg Goblins, which are mentioned in Reavers. One of the character's foster father was killed by goblins and another is a Woodsinger elf, so they have all the reasons to take on the goblins.
Thanks, I'm running a group of combat heavy players through reavers right now, and was trying to determine if I wanted to take them through this adventure too. I think it'll suit them quite nicely.
Was just about to post the same thing. The first episode mass battle is very interesting. I wish the DM would post a summary of the challenge and the mass combat rules he used.
