Perhaps this is all just the other way around. Vehicles such as the US & German Halftracks, the Priest, the Sherman, and so on, were avaliable as single items before they appeared in the playsets. The same can be said for the Mortar pits & listening post sets. Perhaps the new Sherman Firefly and Howitzer will appear as single-boxed vehicles later. The Sherman Dozer and Porsche-turret King Tiger already are avaliable as single vehicles.
The new box is different for the larger playsets, but I like it! It is, however, VERY similar to the boxes the most of the figure sets, the mortar sets, the Pak-40, and IG-18 gun sets traditionally came in when they first went to the small retailers. So, there really isn't all the much new with the box display, just that 21c is applying it to a product they really haven't applied it to before
