I would tend to disagree about the aimed down the sights issue. There is only 1 gun that I feel its almost completely useless to use the sights, mp44 - the German light machinegun. Other than that its fairly easy to track your targets while you shoot with the sights up.
On a seperate note, I dont want to hear jack from IW and Activision until I see the headline "COD Patch Released". The patch has had on and off release dates for months now. Get the patch right and get it out, and quit toying with the public "After Thanksgiving" yea WAY THE FRIG AFTER THANKSGIVING.
