When will the Nikon D400 be brought out?

And how much roughly will the D300s be after the D400 release?

I don't know… But the D5100 should come out any day now.

I'm expecting it really soon. D300s is end of live and starting to disappear. I honestly don't see much of a pricedrop happening, there's too little in the distribution channels for that.
