The same could be said about CoH 1.
Did COH1 editor allowed you to do anything your heart desired??
I'm not saying nobody will buy it , i'm saying that a lot of people will stick with COH2 for a great while until COH3 would be play worthy.
For example when BF5 came out the price was like 100dollars. I was still playing BF4 (which was better than the new released unfinished BF5) until the price went down and bought it half price. If BF4 would be crap I would of payed full price just to get the new game.
