I've been looking at the Nikon 28-300 as well. For a DX though, a 7000, I think it'll fit in with my 10-24 really well.  I have the 18-140 as well as the 70-300.  I never use the 18-140, basically the only time I use it is when I force myself to take only that lens.  Right now I have the gap between the UW and the Telezoom filled with primes and putting the 18-140 up for sale.  
Does the 28-300 compare to the 70-300 for the average shooter, not a pixel peeper, not a photoshop addict, just a regular guy that tries to get it sharp and right in camera without fussing about.
