If you intend to print them larger than A2 then yes you may need one of these very high resolution bodies* but if like me you only plan to use the images at up to 1024 pixels on the long side (for display on a computer monitor) then even at a lowly? 12Mp, you have to down-sample x4 times to reduce the image from 4256 (D3) to 1024.
The main advantage with the FX and more recent bodies is the vast improvement in high ISO and dynamic range. The larger sensor (and larger photosites) makes the camera more forgiving. The smaller photosites of the very high resolution bodies makes the camera less forgiving, demanding a sturdy tripod and the very best lenses to get the full benefit of the very high resolution.
*I have printed larger than A2 from significantly cropped D200 10.5 Mp images and the flower detail and IQ held up very well and have been admired by critical viewers. (The generally accepted recommended viewing distance for pictures is 1.5X the diagonal)
