The body is simply a D7000 one and it is hopeless for a 2000 pus camera. The construction cannot be compared to a similar priced D700 or 5DMkII.
When the rumours started, it was supposed to be priced $1500 which could be reasonable. But why would you want to spend 2100 buck on am amateur body when you could get 5DMkII or D700 (if still around) for a similar or cheaper price.
I had my grip on D7000 squeak and flex when I hold and move, send it twice to Nikon sevice to finally fix it.
The front is a cheap plastic and very thin near the battery door and seems to be a common issue(unless the changed it on the d600).
should be good based on the samples but still doesn't justify the price, the D300/s is a much better body.
The handling would not be good on the D600 and I am sure professionals/semi used to D700 or even D300(s) will not like it.
Appeals only to enthusiasts.
