I own the 85mm f/1.4G, and I plan to test it against the 85/1.8G, but I am deferring testing until the arrival of the Nikon D800, which I hope to receive on April 5th.
At about $500, the 85/1.8G is far less costly than the ~$1700 85/1.4G. Yet it might end up performing nearly as well, since an f/1.8 lens is much easier to design and construct than a f/1.4 lens.

The MTF chart looks promising. But Nikon provides MTF only for f/1.8, wide open, and this is 10/30 line pairs per mm (a bit silly). Zeiss and Leica provide 40 line pairs/mm, a much higher bar.
