The idea that John hardly designed for Dior anymore honestly doesn't surprise me, but I would hate to have the assistant take over.
Dior needs a major shake up. Considering all that has happened within the last few days, I imagine LVMH wouldn't want Dior to continue in the same direction in order to avoid any further associations with John Galliano.
I think the idea of Rodarte is rather exciting, to be honest. I feel like the house needs a new team that can stay for a good number of years. The last thing Dior needs is a Valentino-esque fiasco on their hands (which also makes me think Alessandra would be great for the job). Also, I cannot think of any other new-ish designer who has the capacity and individuality to give Dior a new, strong identity. The Mulleavy sisters have proven their versatility as of late, what with lower priced lines, more commercial collections, movie costumes, red-carpet gowns, etc. And imagine what they could do with Couture (considering their RTW is practically Couture as it is!). We may have come to associate them with all that is gothic, weird and avante garde recently, but let's not forget the elegance of their earlier collections like Spring/Summer 2007 and Fall/Winter 2007.
All in all, I'm sad to see that this is the way John had to go. I was ready for him to leave Dior for a good while now because all he was doing for the house was consistently tarnishing his once magnificent legacy...and this whole disaster has done nothing to help that deterioration of a once great talent.
