I know they didn't say "in RAW", yet it seems odd to me that they would say "20.3 megapixels when shooting in medium" etc., and be referring to jpgs.
To be honest, I never save in jpgs until I have processed and am then saving to send to someone or post on a website. When you shoot with your D700 "in medium" you are still using 12.3 megapixels, which are then processed down to the medium format jpg. Right? That is why I have trouble understanding how they could be referring to jpgs in this statement.
But, we'll find out when we get the cameras. One more thing to test for.
