I havan't had a chance to check look at the maps yet, but here is some other info I found.
dealing with the invasion of manchuria in 45, this is also a something that isn't covered at all, and it could actually make use of the new Manchokou nation.
tactical level info (this includes alot of detailed maps, could be useful in map design)

strategic level info

if people want to cover lesser known areas, and not focus on more famous battles: stalingrad, kursk. Then this I think is a good candidate. paratroopers were used extensively, could be interesting.
edit: here is another peice of info, on tactical defense, prior and during kursk. (it includes regimental and battalion defense diagrams)
