The direction which you mention is debatable. Their last major (sort of niche) release was the Desert trio - I find all 3 wonderful & own them, with Songe being the best. Most here on BN & Fragrantica did shower praises on these 3 & rightfully so.
As well, many reputable Guerlain aficionados mention Wasser's efforts to bring back the classics to "how" they actually were - this is the direction I currently see the house going. A new edition Vol de Nuit / Vega or the mythical Djedi - imagine it being close to their vintage versions? Of course, it cannot be "exactly" like how these were in the past - but if reputed noses say they are almost close - I'd take that any day.
If Wasser's efforts pay off, Guerlain cannot be replaced & I really hope it goes this way...As well LMVH being a business knows the brand value of Guerlain & why it acquired it - any business will pay attention to this part as well when considering all their options.
