APS-C mode sucks ala Canons.

If you need the best available full-frame Digital SLR, and shoot with Nikon lenses, then the Nikon D5 offers high-speed shooting, and excellent noise performance. If you are wondering whether the Nikon D5 is the best option, or alternatively whether to choose the Canon EOS 1DX Mark II - then at the moment, we'll have to wait for review samples of the 1DX II to become available so that we can see how the image quality compares.

There was a Nikon at Hunt's Photo & Video in Massachusetts and I decided to attend. I didn't bother to get any shots of the presentation but I did get some quick shots of the cameras. The cameras were fully functional but they didn't want anyone to put a memory card in them to prevent people from putting it online since these aren't production units.
Nikon will release a firmware update after shipping starts in March that will increase the 4k recording limit of the D5 to 30 minutes. This info is coming from a Nikon rep.
