D7100  vs D3 

7.8

That makes sense on some level, though, since the 1D Mark III and the D3 are really all-around cameras that combine the burst speed to handle the demands of sports shooters with ruggedness and image quality that should appeal to news photographers and many others.

For that, you can get a D3 body, one of the brand-new Nikkor 24-70mm f/2.8 N-series lenses and Nikon's fabulous 14-24mm N-series wide-angle zoom.
