I still rate the chances of the D400 everybody covets (basically a D7100 sensor in a D300s body, with 8+fps and the D4 AF system, all for $2,000) as less than 50%. Perhaps way less.
But, the interesting part of that rumor is the "new AFS 300 f4", presumably with VR. That, I would love to see. I have wanted to buy a used AFS 300 f4 for years. They basically don't exist except at prices that rival buying new. I don't need VR, but a lot of shooters do (or think they do), so a new VR version would likely put a lot of used non-VR versions on the street,...and for a much more reasonable price.
