The airborne vid looked good, they seem to have a breathing system in for sniper now, prolly similar to cod 2 where you hold shift to steady your aim for a few seconds. Dloading the second airborne vid now, meant to be more sniper gameplay.
Edit: second vid here

Kinda reminds me of that level in mohaa where you had to go through the town and clear out enemies then the tiger would come up to the bridge and you had to call in artillery to take out tanks and stop germans from blowing the bridge. Right at the start if you look to the right theres a large bridge, looked pretty nice graphically and thats just the 360 version they showed.
