The only one I can think of right now is Agent Provocateur - the very first one in the ceramic pink bottle.
Consumers these days don't like anything out of the norm so we get a whole lot of generic floral/nauseatingly sweet food smell (vanilla and chocolate are very popular) - inoffensive, but bland. Very often, the complex and interesting one doesn't sell and end up being discontinued.
I'm more worry about the re-formulation of the "classics". My beloved No. 19 has already been butchered and doesn't smell quite like it used to (and what's with that ghastly green color?).
