gucci is trying hard to go back to what it used to be, it is true.
Frida stated so many times that she wanted to move away from it, that it is now a bit shameful to do it so blatantly, specially in some of the menswear and her last two collections for womenswear.
but, the change in the bags however came from "above" this time around.
apparently, monsieur Pinault (owner of the group) is more and more concerned about the environmental impact of his labels; or his wife is, actually...
anyway, the thing is he now admittedly and religiously follows her advise and he does things like driving a hybrid card, and "unglossing" shopping bags (making them 100% recyclable, no toxic colorants, etc.) and there you have the answer for the new bags!
EDIT: about the envy me thing, although it's very close to Fords departure, it could easily not be 'his' project. Developing new perfumes takes a lot less than we would like to think (or pay for unfortunately) and in gucci's case, it's Procter&Gamble how does all the fragrances (P&G=great power for developing and marketing new products in the blink of an eye)
In Ford's era it would've been him having the final yes/no... but specially with the change of powers when he left, and helped by the good economic performance of the new product, I don't see why they wouldn't have allowed it to continue under their portfolio (no matter how product and brand image related).
