Actually 4 FX bodies (D4, D800, D800E, D600) and 1 DX body (D3200) have been introduced this year. Frankly I am starting to wonder if there will be a D400 at all. That said, I would like to see a D400 as well. Since Nikon is so good at keeping secrets, we will just have to wait and see what happens. Good Luck and Enjoy your Nikons!
