I just saw the new North Africa campaign book, which replaces the old "Afrika" one.
It is a real monster of a campaign book. Its hardcover and about the size of the main FoW rulebook. Full color throughout, with the new style army list layouts and unit descriptions. A much more impressive book than even Fortress Europe is.
Its a real step forward compared to the old one, and the upcoming "Eastern Front" book is apparently getting the same treatment, replacing the old "Ostfront" book.
