The tall prism head looks interesting - wonder if it'll be 100% viewfinder coverage. The thing that infuriated me most about the D700 was the 95% viewfinder coverage - with only 12MP to start with, losing 5% outside the frame wasn't good for large prints.
The mode select button is identical to the D7000, although why anyone who wants an FX camera would want scene modes is beyond me. The remainder of the layout is very akin to the D7000, with the same AF mode selection that was adopted from the D7000 into the D4 and the D800.
Makes me wonder if Nikon has decided that the days of the pro/prosumer DX are gone in favour of FX. I'll be disappointed if they do go that way - the biggest advantage of DX for me is the 50% extra free mm you get with telephotos. My Siggy 500 f/4.5 on a D7000 gives me more reach than the Nikon 600 f/4 would give on a full frame body, is almost as fast and is about half the cost.
