My hopes are high on this one. That being said we will always be comparing it to classic CoH (wehr/american) and I'm not sure it would be wise to do that since CoH2 is trying to capture the war on the Eastern Front and the challenges those times brought to both army's.
As 12azor mentioned in his article it "feels" like CoH. So as long as they don't stray too much I think it will be okay, but different.
War on eastern front was a bloodbath. In a game standpoint if you were to try to make both armies realistic to this war Germany will have such a superior army that USSR should almost always lose unless the player builds about 10 times more infantry and just blobs them to win. Which is essentially what Stalin did to win.
