If EA can manage to sell Battlefield 1 with italian and hungarians, the relic can manage to sell CoH3 with afrika wehrmacht, brits, early war US and italians.
All that CoH fans care about is the WW2 setting and good coh gameplay. CoH2 launched without a king tiger or sherman tank after all and still sold well.
I think the game was Panzers/Panzers2 that were really good and in that scenario.
