Although i'm very much looking forward to SOW I am in agreement with some of the other chaps here about the landscape, and I hope it'll get updated, i'm sure it's a long way from complete. Those screenshots from WOP look far more realistic to me. British country roads are mostly single lane with passing places and lined with hedgerows, or hedgerows and trees. Spots of bushes from time to time just don't look realistic at all.
I'm surprised nobody has mentioned the fire effects, at present they look poor (check the aircraft on fire @ 2:11 in the video) - but I think it's too early though and will get fixed.
Check out the way trains explode - the power of .50cal rounds - fuel tanks going up on static and flying aircraft - the 'sparkle' as rounds hit the target - deflected tracer from the ground - the dust and smoke thrown up on the ground from the rounds that missed - the bits falling off the aircraft in flight as it is torn apart. All of this is done pretty well in IL2 now with the effects pack mod, but we want more
