I agree with Johnny Apple's post. Maybe not his suggested zoom range, but I'd like to see a new FX VR zoom lens that can replace the 24-120 lens. Nikon's VR zooms are lacking for full frame I think. Older glass and of course the 24-70 is all thats currently available. Fortunately Nikon has made a lot of incredible primes. People have discussed this often.
The rumour of a new 16-35mm wide lens with VR would be great as well I think. This would replace the classic 2000 year 17-35mm which would be nice. I hate the fact that you can't use filters on the 14-24 lens except for the Hoya $700 system. My 2 cents.
