I just don't get the idea behind a D600. Why cut down what would be a D800 to make it a D600 (or D800 lite)? The D400 makes sense as the D300 is very long in the tooth. Nikon really needs to get that camera to market this year. I, for one, will buy one to compliment my D800. And I don't expect it to come in as low as the reported $1800. My guess would be around $2,000.
