If D800 support does indeed need to wait for Aperture 4 (and I don't suspect that it does, but someone made that assertion) then that means one of two things: either Aperture 4 arrives before the D800 (like the RAW update arrived before the D4) in which case we get a new camera and new software and it's Christmas in March, or Aperture 4 arrives after the D800 in which case life sucks because we have a new camera but have to muck up our whole workflow to use it.
Ahh.. I was thinking there was an announcement of A4 that I missed. Thank you for the clarification.
