Actually all the new features they included are the biggest critics the playtester have for this game: True sight, campfire, weather effects and tank capture are only a few examples of what is going to make the gameplay problematic. What is left is basically coh1 with a new faction. If we take a look at this new faction you have alot similarities to EF mod. So basically coh2 and EF mod are competitors for players. EFmod has the older engine and less possibilites to improve the gameplay, but tries to keep the original vcoh gameplay, which made this franchise so great and popular.
