Since it's pretty much a foregone conclusion that the next expansion, if there's to be one will be an Eastern Front based one, I have but one request to make to Relic, just one.
Please, for the love of God and all that is 1337, do not make the Soviet faction based on stupid Hollywood movies like Enemy at the Gates.
Russian soldiers were not used like cannon fodder, they were not deprived or rifles and they were definitely not short on artillery or tanks.
I have this ominous feeling that I'm going to see a Soviet faction ripped straight from the biased stereotype made up in the West (mostly as a way to raise the morale of NATO troops).
The Cold War is over, there is no more need to insult the Russians.
The Red Army, especially after 1942 was a competent, well organized, very well equipped fighting force capable of taking on German forces in 1 to 1 settings. Don't insult the memory of those 20 million Soviet citizens and soldiers who died to keep Europe free from Nazism by making a game that's based off some silly American propaganda film.
