Why No Nikon f1.2 G Lenses?

Oh, and a couple more things:

• Weather sealing
• Smooth bokeh along the lines of the 85mm f/1.4 (the current 50mm f/1.4G's bokeh is not terrible, but it's not exceptional either).

Essentially what I'm asking for is the 85mm f/1.4G in a 50mm-60mm body, with better wide-open CA performance and closer focusing distance.
