It's true the pleats had disappeared from the Feldbluse by 1942 (but obviously many soldiers were still wearing the earlier patterns well into 1943). By 1944 the Feldbluse didn't extend past the waist - it looked more like a British battledress. However, I had assumed that the idea was for these figures to be generic mid to late war types - as someone pointed out earlier, there was a lot of variety in late war uniforms. Also, if the pleats are removed, it's more difficult to convert them into Afrika Korps (Afrika Korps soldiers didn't wear gaiters, but that's fairly easily taken care of).
Warlord have gotten these details wrong as well - look at their initial 'late war' Germans. I think to many people the pleated pockets an iconic feature of German uniforms.
