I will be posting additional information on the Nikon D600 that was announced earlier today in this post. There is a lot of information, with some sample videos coming from everywhere, so I recommend coming back to this page to get more updates.
Along with the D600, Nikon also announced the UT-1 transmitter that is used for both wired and wireless transmission of images. The official page that describes the unit is also at Nikon.com.
Here is the official video for the Nikon D600 from Youtube:
Nikon Australia also posted the following time lapse from the D600:

Sample images from the Nikon D600 are provided at Nikon USA as well, but the page is extremely slow/down at the moment.
