Brian's analysis is spot on, and goes to show how expressing the sensor area using a single dimension (megapixels) works against you in apparent gains in resolution. Doubling the megapixels will result in a 40% gain in linear resolution (which is precisely the gain you'll get with the theoretical 24MP DX D400).

Let me throw something else out there, although if the D7K's AF system isn't up to your standards this may not work either, but Nikon V1 10MP CX crop represents a 62% increase in linear resolution over the D300. That kind of increase is something you're not likely to see from DX or FX for a very long time.
