In my opinion, the dev team is secretly working with Chuck Norris, whose is doing this fabublous work by his thinking
All it would require would be a single roundhouse kick from Chuck. Then, in the next update after 2.26, we would have not only the rest of Normandy and the entire Battle of the Bulge, but Operations Market/Garden, crossing of the Rhine, and battles beyond the Rhine; Eastern Front complete with Winter/Continuation/Lapland Wars, Invasion of Poland (including Westerplatte) and Hungarian front (without forgetting Italian and Romanian troops); the Pacific along with the Japanese/Soviet front and China, complete with fully working movable battleships; early Western Front; Italian Front; several French Resistance/Polish Underground State/Yugoslav Partisans asymmetric warfare maps; several "homage" maps such as Escape from Wolfenstein, Schloß Adler, Assassinate the Führer, Mosquitoes in a Trench; and finally we would have Alpenfestung Mk 2 (featuring Ratte) and Operation Highjump.
Since this has not happened, it obviously means that Chuck is, unfortunately, concerned with other things.
