Well, seeing that so many fragrances are being retired, I just hope that they replace them with other fragrances from the Salon range. So far I only heard about Cuir Mauresque; another knows if any others are coming out?
MKK was the "one year limited" and it's replaced by Cuir mauresque for the next year.
Vetiver wasn't an unlimited 50ml realease when they begin to export it (as Bois de violette, bois sépia).
Fumerie Turque will become a permanent export now (as fleurs d'orangers, chergui...)
Concerning Santal blanc , chypre and douce according to a SL interview it's purely for commercial reasons (like Miel de bois in 2009) and it's not his own choice. I'm surprised too because douce amère seems to be accessible but apparently not...
