Here's an interesting thread to add to the discussion.
There are many more out there, basically the Nikon D700 is such a great FX camera that older lenses which performed poorly on DX have become much better on the Full Format D700. So called poor lenses have been given a new lease of life.
On the other hand, the technological improvement of cameras may also necessitate the development of even better lenses. For e.g., the Nikkor 14-24 ultra wide lens which is stellar in the corners on a D700 FX and DX cameras has started to show its corner weaknesses on the current Nikon Flagship camera, the D3x.
