Well, maybe the time to retire my ancient D70 has finally arrived. I am particularly intrigued by the 1.3 crop mode and am looking forward to hearing what the reviewers have to say about it.
so does this mean that if you use a 300mm lens you get the benefit of the normal DX crop (1.5x) plus an option to crop by a further 1.3x? Is for you 300mm lens = 585mm...?
The 1.3x crop on DX translates to a 2x effective. A 300mm lens will have the same angle of view as a 600mm lens.

Does that built in crop factor of 1.3x also crop the Mp?
i.e. Will that 600mm (effective) from a 300mm lens be @24Mp, 18Mp (linear crop), or even 12Mp (area crop) ??
18mp according to what I read in one of the documents (I can't remember which one) linked to in the OP. My mouth is definitely watering.
Resolution is 15.4MP (4800x3200) in crop DX mode.
As for figuring the effective focal length of a lens in this mode, best to understand it like this.
A Nikon FX sensor is 36x24 aspect.
A DX sensor is 24x16.
This new crop DX is 18x12.
As you can see, the ratio between the FX and DX crop aspects is exactly 2x. Thus a 300mm lens will have the same angle of view as a 600mm.

I wonder if the new 7100 still has the crippled frame buffer seen on the 7000?
Not sure why are people so much excited about the 1.3x crop mode. In fact it is not 1.3x crop. It is crop of the crop 1.3 * 1.5= 1.95x crop of the full-format.
There are no 1.95x lenses so there is no point of having it in the camera (unless you cosnsider 7 vs 6fps diffrence as significant). You can always do the crop in the postprocessing.
I would rather welcome equivalent of Canon's sRAW rather than crop.
