Look, they are following the same concept of the prequel, but they can't make a whole new interface for Warfare 1944, with different intelligence, new physics etc. otherwise it couldn't be called a sequel. They added a lot of new stuff, like the way you can shoot people who are on different paths as you, paths, new weapons, etc. etc. And the first mission was AWESOME because of it's difficulty. Great game.
It is a great addition to the series. If there are plans for another one after, I would suggest the ability to move the soldiers by mouse click. You could advance them to the next strategic point, or you could click on a point in front or in back. There definitely needs to be a retreat option. But it is a great game. 9.5 out of 10
