Well I just got back from shopping and did go for the black one

Factory low battery got depleted setting up the menus and AF fine-tuning a few lenses, so it's on the charger now. And they had no extras in stock, about a week out.
Anyway, a few comments. A 64G card looks like it will do about 1400 RAW+LgFine jpgs, or about how long the battery is supposed to last.
I am really impressed with the control layout -- amazing to me that Nikon could build a camera smaller and lighter and that looks so cool retro, yet all of the main controls fall almost right where they do on a D800. Love the fact this one does the 100% zoom on review with the Fn button too -- I seriously wouldn't have bought in if it didn't.
This could be the ultimate travel cam; smallish, light and easy to use while producing phenomenal files.
It may just be me, but does anybody else think the AF seems a tad bit faster than even the D800's? (Frankly surprises me if it is.)
I agree with the comment above about it becoming an instant favorite. I honestly bought this as an indulgent toy, albeit one that would look cool and had the ability to produce phenomenal images when I wanted a casual camera. What I got may still be a toy, but it fits my hands and works much like my other goto workhorses. I like it enough, I can see a future where another one of them may displace one of my D800 bodies...
