Possible also because the primary American effort was in Europe and more veterans served there then the Pacific, Southwest Pacific and China put together. There being about 28 Army and Marine Divisions in the Pacific and about 75 Army Divisions in the Mediterranean and Europe with both theaters having about the same Air Corp slice. Meanwhile the Navy was different but in the end that is the story of a ship surviving or not not the man or unit of men.One of the oddities of history is that today when someone talks about WW2 the average american thinks of Europe. During the actual war years most Americans were more attune to the Pacific theater.
This is likely due to TV and the movies that followed the war. The European theater was much easier and cheaper to make movies about. The settings could easily be varied (A town could be France, Holland, Italy, Germany, etc) while islands look alike and few could relate to them. Ships were ships, one submarine looked like the next.
I still think a show about the Enterprise or at least a fleet would have been awesome and different enough from Band of Brothers that no one would make that comparison.
Of course, there are a lot more stories that I would find interesting that most Americans would not (Japanese Americans serving in the Pacific for instance), but I understand that you make an expensive WW2 series you want to reach the broadest audience.
