I have been thinking of replacing my 4 year old D 80. It's still a fine camera, but I'd like to step up. I was thinking the D 7000, but it seems to have AF problems on some of them and oil spots. I'd like a D 700, but I don't like the price. I am therefore considering a D 300s or the D 400 when it comes out. I'm not in any great hurry to buy. Is the D 300s better in some ways than the D 7000? And will the new D 400 be better than the D 7000, if it has the same sensor?
