After thinking about it some more... how the heck can Murphy's wife be the female lead in this remake?
Murphy's wife didn't DO anything in the first movie except be in a couple of flashbacks. Unless this remake is 90% Murphy and 10% Robocop, it seems like she wouldn't have much to do here either.
Lewis was the female lead in the first movie. She was Murphy's partner and the only woman that actually got any development in the entire thing. Besides helping him out she was pretty badass.
Maybe that article simply got it wrong and they meant important role instead of female lead?
