Yes, that is still an issue even now. It's amazing how long each of my 8Gb cards take to download once they are full with 305 14 bit RAW images!
I just can't imagine being able to use ISO6400 with the same low noise of the D700's ISO 2000 or thereabouts, but I am sure it's be nice!bingo - As much as I wanted the D700, after seeing the D3s high ISO performance, I can't see myself upgrading to D700 until the D3s technology filters down, or i save enough to upgrade to two D3s (as i can't stand shooting with two different bodies)
