Come on Nikon - give us a true D700 replacement

The D600 is nice and all but is not a legitimate companiion to the D800 or D4.

Please give us either the D600 or D4 sensor in a D800 body with the pro AF, 1/250 sync and a burst rate of 5fps or more.

I love my D800 to bits, but I want a more respnsive camera for weddings and events. The D700 was brilliant for that, but is now dated and needs a replacement.

You've admitted that the D800 is not a D700 replacement, and you know the D700 market segment is a real one, so when do we get it?
