From update # 12 :
Devil Pig Games will be creating an official expansion to be released Winter 2014 for their Heroes of Normandie game, titled Achtung! Cthulhu: Shadows Over Normandie and this will be part of an exclusive offer on Kickstarter if they hit their £30 k Goal.
Winter 2013/2014 might be for the other (historical) expansions ?
Edit: Maybe there is a typo in update #12 ? That would be sweet...
