Nikon specifically claimed in a release to dealers that the new lens
was specifically designed to give a pleasant rendition of out of focus
areas. If I can find it in our "filing system" I will quote the words
that were used. However, I think it was probably a reference to the
increase in the number of diaphragm blades and the fact that they are
now curved.
Nikon loves to concentrate on what metal diaphragm blades do, when
everyone should by now realise that bokeh is a quality obtained not
from metal, but from glass.
You cannot disguise harsh bokeh with fancy diaphragm blades - the
shots Rich linked to clearly demonstrate that. However, a crude iris
diaphragm will show up a case of harsh bokeh for everyone to see.

If you need to choose a background to suit the lens, that implies the
lens has harsh bokeh. Using a lens with smooth bokeh means you don't
have to worry about the background; even backgrounds with specular
highlights can be defocused into mush.

On the contrary, there is significant variation in bokeh between
brands, and between different designs within brands. Bokeh may be of
little importance to many photographers, especially those who shoot
through crappy consumer junk lenses at f/8. However, it is likely to
be of great importance to the majority of buyers of expensive 85mm
f/1.4 lenses because of their intended use as classic portrait optics.
