Deformable terrain on an engine such as this would be damn near impossible, especially for a game that had huge performance problems at the beginning, a good idea, but i think its not in their best intrest to put it in. Looks like a great game to me. The guys in the 5th screenshot need a grenade
One thing i think that would be cool is to develop a cool way to do napalm, and maybe a flamethrower. These were extensively used in WWII and didnt make the cut for bf1942, maybe theyll be used in the tunnels of vietnam.
