Very busy week - those rumors just won't stop (check the latest Leica and Sony rumors). Back to Nikon: there is a new Nikon patent for what it appears to be a 85mm VR DX lens. This patent is not yet listed on Google Patents, but can be found here. Maybe somebody more technical than me can interpret those formula and numbers.
Patents applications do not necessary lead to a final production model.
FIY Nikon has released 3 DX and 1 FX lenses this year.
