Not believing this until I see the official press release statement from Dior.
Maria turned Dior into one of the greatest luxury cash cows, no way they're gonna let her go so easily.
I don't think there is a problem with her willing to go back to Rome, she rarely is in Paris or in the ateliers whatsoever, we know that most of the actual work is done by her close assistant "right hand", the woman you see in every "making of" video.
She's not different than a Miuccia, she just provides inputs and inspirations and then let the design team come up with proposals that she validates.
