Does the D7000 actually have wet lubrication that could conceivably get into the mirror-box, and then deposit itself onto the sensor?
I would think something amiss like this would have to be involved with the shutter blades. Could wet lube drops coming from elsewhere float around long enough to wind up on the sensor? Wouldn't they have to be almost like in an aerosol form to do this?
As a test, clean the sensor, put on a clean prime lens, take a base-line image (doesn't have to be perfectly clean). Throw on the High speed shutter setting, shoot in Manual, and zip off 100 frames of a blue sky (or like subject) at f/22. Then look. If the camera is generating the issue, I'd think you'd see dots increasing in the frames.
That being the case, I'd send the images and camera to Nikon. If not, then I'd look elsewhere for the root cause.
