Ha. I've just figured it out. We're all wrong.
It's not oil. It's not dirt. It's not that Nikon's manufacturing has taken a big hit (those pictures of the 10 pin connector falling into the body of various D800's - photoshopped).
There are Diffraction Dots (TM).
Note that they only show up at smaller apertures. Just where the phenomenon of diffraction artifacts appears. They are cleverly designed by Nikon engineers to show you when you are stopped down too much. Clean them off and they'll come back in a week. But open up the lens and the problem disappears. Get that $2500 f/2.8 lens and the problem doesn't show up in the first place.
Pah on Thom Hogan to think that Nikon's marketing folks don't know what they are doing.

hmmm would be nice if that was the case, but also making me panic!
Well i didnt notice it @ 2.8 indeed on the 70-200
but what worries me is i just recently bought the 200-400 vrII and if its gonna be noticeble in the field at f5.6-f8 im gonna get dizzy
The weather has been bad here lately, so i have not got a chance to extensively test in the field:(
some at other apertures
also isnt it a bit weird, that the spots show up at the same place for the 70-200 and 200-400?, and that it's such a random pattern?
still thanks for the suggestion that it might be or 'is' diffraction!
