Why No Nikon f1.2 G Lenses?

At a normal portrait distance, say 2 metres, the difference in depth of field between a f1.2 and f1.4 85 mm lens at their respective full apertures is negligible, and the gain of half a stop of light has become of little consequence, except in the most extreme conditions, with current sensor technology.
