All we can do is guess, but my guess is the D400 should be announced soon. I'm thinking D300s sales should slow to a trickle, some lost to the D7000, and some to people who will wait for that level of performance in a DX00 body. The D300s is a great camera, but you'd have to pause before paying more for a camera that doesn't have the image quality of a less expensive sibling.
