Kind of early to tell - not having the game in hand yet. Will come back later. all of the above sounds good.
The expansion that I would like to see would remain in europe (yes I want pacific too but lets wait until europe is done.) I would like it to be called "Stalingrad To Berlin" with a focus on the street fighting that occoured. So we would need lots more building and city sections. Blown bridges, barricades, volkstrum, fire, smoke, rubble, Also I would like the mission editor to be able to use all maps and objects with placeable building- trenches and the like.
