After the first new list (the Woodmen of Mirkwood), the whole thing just got a notch bigger: Make army lists for the races that don't appear in the movies (or change those that are just crap).
So, work has started on the Wilderland Army Book, for now only in German. These are not just alternate profiles, there's totally new armies to build: Beornings, Léofring, Woodmen, Wayward Elves and Orcs of Mount Gundabad. Dale and Lake-Town will get new lists, that work better with those towns in later years (and don't look as shit as in the movies).
Working with Dark Ages models, the whole thing transports a look that is a lot closer to the books.
