Nikon hasn't made any new MF designs except the new PC-E lenses. So they are the same lenses as in 80's, just upgraded with newest coatings (not nano coating though).

My secret dream is that Nikon some day releases a new manual focus Ai-P lens collection using the newest optical designs used in 24/1.4, 35/1.4, 50/1.4, 85/1.4 etc.
