In the 1D3 domain, FF is a clear DISADVANTAGE...

D700: full frame, 8fps with grip, low noise, 45 point autofocus
closest canon has is 1DMk3 but is cropped sensor
---->Will canon make a full frame 1dmk3 (not 1dsmk3 b/c too low fps)
THIS IS NOT A CANON VS. NIKON THREAD WAR... please only respond with any insight into what would be comparable from Canon
...Nikon's true direct competitor to the 1DMarkIII is the D3 (not the D700). Furthermore, and once you are on the field, everything gets longer/heavier/bulkier optically-speaking (and not IQ-better though) with a FF sensor, whereas with Canon's APS-H 1.28x sensor you cream the best of your lenses, you can user shorter (and more state of the art ones) or simply get even further ahead without changing your 300mm or 400mm, and all this with same (or better IQ).
For the above reason, the 1D3 proposal is inherently more efficient and better engineered for the core tasks... unless, of course, you most likely need to go wider, still with poor light, and that is an area where a FF sensor would excel.
Don't be surprised if the next 1D4 comes with a FF sensor but a crop-mode that offers same resolution/density than current 1D3, though.
