I did not see a single preview of the new Nikkor DX Micro 40mm f/2.8G lens online, which is highly unusual compared to previous product releases. There were no YouTube videos, product shots or sample photos taken with the lens. As far as I know, there were no press events scheduled around the world where the major industry players could have a quick hands-on with the new product. My information is that nobody has seen or touched the new lens. I could only find some more sample images from Nikon Australia, Nikon India and Nikon France (on flickr):
and some more samples from the I am Nikon blog:
