Re: The Star Trek Into Darkness teaser trailer is here!
I wonder if J.J. will show ridged Klingons as well as smooth-headed ones to preserve at least some continuity. If not it's always possible that in the altered timeline after 2233 the Empire found a cure for the effects of the 22nd century viral mutation seen on Enterprise
so there might not be any smooth-headed Klingons left by this point in the new history.
Human instinct is pretty strong. You can't expect us to change overnight.
