I could get hit by a truck tomorrow. If they're truly amazing fragrances, may they release as many as possible, as fast as possible!
Honestly, on the subject of en masse releases, I haven't found a direct correlation between quality and number of releases. Tom Ford released his Private Collection all at once in '07, yet I haven't found any of the one-at-a-time additions to the line since to be better than most of the original line.
Mozart's Symphony No. 40 took a few weeks to write. If these Diors are deserving of the praises Octavian is giving them, I look forward to getting my hands on them.
