I also think it is a fantastic idea to try to recreate something that is now only a legend, provided that the attempt is in earnest. I also wonder about the validity of smelling some 60 year old vintage juice next to a reformulation, and dismissing the new formulation as a failure because of some dissimilarities. I am not a chemist, but I would bet that 60 year old juice is only a shadow of its original self (most 60 year old objects are). I have had many fragrances take a turn for the worst in less than a decade. I think Le Labo's expiration date is a little excessive and unnecessary, but they do have a point.
I, for one, cannot wait for my bottle. Near, far, weak, strong, similar or dissimilar to "vintage" Fougere Royale, the new 'formulation' can stand on its own.
