I've already stated several times within this forum that in reality in the long term, a full frame sensor is probably a handicap. I see absolutely no drawback to having a 1.5x sensor aside from having to purchase a 12-24DX, and would love to hear from anyone with a disadvantage. On the other hand I can think of plenty of advantages.
I believe the camera will use the CAM900 sensor, although I am not sure and a CAM1300 sensor would be a bonus as far as I'm concerned. But I do not consider this a major factor even given the work I do. I have used a D100 with screwdriver lenses for work, and while it is not ideal, it shouldn't be an excuse for not being able to deliver good pictures either. And with AF-S lenses there is very little to fault with the CAM900 module. If you need it for even more exacting autofocusing performances than me then fair play.
Larry, a lot of your questions can be answered by hopping over to Kodak's website. I don't have the link offhand and I don't have the bandwidth to dig it out, but www.kodak.com and then navigating to "Professional Photography" and onwards to the DCS 14n will get you the required information.
Questions for Kodak?
 Why was the image size dropped from 4536x3024 to 4500x3000?
 Is the frame rate 1.7fps as widely circulated, or (up to) 2.5fps as stated in the camera's manual?
 Any theories or explanations as to the camera's apparently poor capture of hair detail, as per the pre-production samples on the Kodak website?
 Can you confirm or deny that the samples on the Japanese website (http://www.i-inc.jp/DCS-Pro14n/14n.html) are indeed DCS Pro 14n samples, or fakes? (It has embedded EXIF information which you should be able to examine) In particular the comparison images with the EOS1Ds and the sample of the painted mask.
