Well, I think we could do a Kursk event next. Granted we would have to use a different map for the event, but I think the time has come.
We have a decent line-up for aircraft, and GV's, and most importatnly, with the arival of the Ju-87G-2, both sides will have a good ground-attack aircraft available.
One of the benefits of doing Kursk is that its one of the few setups we can run where the Germans are on the strategic offensive. Really after that point, the Germans were at best using agressive defense. Even the Balaton offensive wasn't really strategic in nature, it didn't put the initiative back in the German's hands.
It seems like the GV setup is going to be hardest, since we don't have AT guns, mines, and all the other defenses the Soviets had on their side. IMO, for GV's, we would give the Germans: Panzer IV F2/H at a 2:1 ratio, one group of Tiger I's, and a group of Panther G's, in substitute for the Panther Ausf. D.
Soviets would get the T-34/76 and the T-34/85 in place of the Su-85 and their AT guns. Numerical advantage would obviously be given to the Soviets in this case.
