This morning's Louis Vuitton show was, as rumored, Marc Jacobs' last for the brand recently named the most valuable in the world.

After years of speculation (remember that "retrospective" from 2011?), Jacobs, Robert Duffy and Bernard Arnault confirmed this morning that Jacobs would bid adieu to the French fashion house to focus on taking his namesake company public with an IPO, expected to take place in the next three years, WWD reports.

A successor has not officially been named but... *cough*Nicolas Ghesquiere*cough.*

Whoever it is, though, will have the pleasure of stepping into a pretty successful, relevant brand thanks to Jacobs's transformative influence over the years. They'll also have some pretty big shoes to fill: Jacobs's runway shows for the house have consistently been the most over-the-top, talked about shows of fashion month. And his iconic collaborations with artists have left indelible marks on the worlds of fashion art, and pop culture. It will be interesting to see whether those facets of the brand will continue, as well as Sofia Coppola's coveted handbag collaboration.

It's a big decision for all involved, as Jacobs, Duffy, and LVMH each own one third of the Marc Jacobs brand. And it means that Marc Jacobs is most likely about to get huge, with the inevitable addition of new products, categories, retail, and more.

We can't say we won't miss him at Vuitton, though. And we're sure Paris will miss Jacobs.
