I think it's a bit late to ask for this on a D4. Assuming an August announcement, the camera must be in or very close to production tests by now. If the consensus is for something other than what Nikon has decided on this would be more applicable to the D5. Assuming Nikon is listening, that is.

WoW! Can you imagine what the D6 is going to be like?
4 slots for Terabyte + SDZC class 200 cards. 96 megapixel CMOS Reduced resolution shooting all the way down to 9 megapixels. 9x16, 2x3, 4x5, 4x4 crop modes. 24 fps stills 240 fps Video 3x4 inch LiveView LCD that you can read in bright sun light. Built in GPS and WiFi. etc.
This question clearly isn't addressed to me. I'm not going to buy a D4. Right now I have a D50, which uses SD cards, and a D300 which uses CF, so I have a lot of experience with both.
One difference is that CF cards have 16 bit transfer and SD cards 8 bit, so potentially, CF cards can be twice as fast as SD. With all cards getting faster, I'm not sure how much this matters, but it is a reason to stick with CF.
One thing that bothers me about CF is the connector pins in the camera, which have the potential to bend or break. SD cards don't have pins, which appears to me to be a big advantage. For that reason I would not be upset if my next camera used SD.
