Agreed with your 2nd and 3rd points. I agree with your first one, but I am not sure if I like the way it is presented. While I believe that a huge marketing tool of Armani scents is their trendiness, I also think that AdG, LEau DIssey and all calone based fragrances are essentially nice and likable for any untrained nose. They do not need to be pushed to sell (e.g. it is easier to sell Harry Potter than Ulysses by James Joyce). Another requirement for your first premise, IMO, is brand image and prestige, which is not exclusive to Aquatics. i.e. Why push only aquatics? Why not push and make trendy gourmands and floral?
And now that I think about it, the 3rd and 1st points are not that different. One of the differences is that the last one is "underground" (?) or upper level and has an image of being more intellectual/exclusive/refined. Also, the third one does not use international corporations, but it does need technological innovation, globalized media and commodity flow.
Unless, I am missing your point entirely.
Also, I would put Trueffit and hill on the group of colognes that are being sold "under the guise of traditional names" but adhering to the most trendy movements. T&H is far from being traditionally English.
