I did the download and updated the firmware in 2 bodies today. All went well. I looked when I went to the Nikon USA firmware page, and as best I remember, it says D700. The D7000 mistake must have already been corrected.
I haven't tried to see if there are any obvious diffences with the new firmware. I just checked both bodies to ensure that they would still shoot and show a picture in the LCD. Both did. Life is good.
