Yes, of course. To make my point a bit more clear: Have you seen Mercedes Benz or Porsche make a "commemorative edition" of any of their cars from 20 years ago? Do you ever expect Apple to resurrect an iphone model from 10 years ago and bring it to market as "iPhone Classic"?!! What Leica - and Nikon- are doing is what a water fountain does when it reaches its maximum height.
I gave a talk at a Safari Club dinner here in Los Angeles a few month ago and argued that sporting optics has reached its apex of progress (as measured by a human user in the field). You can see my presentation slides here:

Omid,
I don't think that you can compare the improvement of Optics used in binoculars, gun sights and telescopes with the improvements to Automobiles or iPhones or computers and such over the years.
The particular Optics we are discussing have an intimate connection to the sight of the individual humans who use them. Improvements of these optics will necessarily reach their limitations as they get closer to the limitations of human sight.
The optics historically used in the 4 different types of binocular prisms (Porro, Abbe-Konig, Schmidt-Pechan and Uppendahl) over the last 100 years and more affected the designs, balance, lengths, widths and weights of the binoculars using them differently.
Back in the 1980s Leica/Leitz did not pursue the improvement of the coatings on their old model Trinovids which used Uppendahl prisms. They simply stopped using Uppendahl prisms and switched to binoculars which used Schmidt/Pechan prisms and this changed their binoculars entire physical makeup.
Leica has now given those old Uppendahl Prisms phase coatings and brought their old Leitz Trinovids back with new up to date coatings on their lenses. This gives binocular shoppers more styles of binoculars to choose from which are lighter in weight, slimmer and easier to carry around.
It is a marketing strategy by Leica and an improvement of the old Leitz Trinovids but it was never meant to be a new revolutionary improvement of binoculars.
