I am disappointed in the refresh of this lens. Nikon doubled the price of the old lens. But the biggest issue I have is that if you want add a @x teleconverter you will be at F11 and no camera body is going to give you autofocus at this aperture. I prefer the Nikon F4 lens which allow me to have autofocus at least with the D600 and D800 bodies as well likely as future Nikon body releases. The 300/4 and 70-200/f lens give more flexibility that the new 80-400mm.
