I will happily take a stab at this one-
Do Romans
Seriously, I think I may get pummeled by a lot of my fellow collectors but I think WW2 ETO- US, British, Wehrmacht, etc are in abundance- though they are selling. If I were to compile a wish list, I would ask for a company to take a stab-a serious stab- at the War in the Pacific- Americans, Japanese and Commonwealth troops- any of the poses you mention would work- attacking/ defending, etc.
I would also like to see more Russians- my Eastern Front collection has been sitting idle for several years now- so idle that I may scrap the collection.
Otherwise, I think AK and those figures have been done to death- add more British EA and US troops into the mix. I think the Italians are sorely underepresented as well. Some of the Italian Tankettes are needed, British Crusader, etc- you get the picture.
BUT BUT BUT- If this were my wishlist- I'd take an M1A2 Abrams, Bradley or LAV Stryker for the GWOT/OIF- but, alas, I am in the minority here.
A winterized Bulge King Tiger would be nice too.
Any of the poses can be worked with- collectors can make the poses work with what they have already.
Take care and as always, great job with everything!!
