When I went to the American Girl store today (last Saturday morning visit of the decade!), I noticed some things about the Girl of the Year section as they prepare it for Joss's debut.
This is what's left of Luciana's section.
They moved a photo of Luciana as a placeholder, since they don't have Blaire's photo op up anymore. (Speaking of photo ops, I can't wait to take my photo with Joss's! It's always fun to see how much taller I am than the cardboard cutout.)
Speaking of Blaire, some of her collection's purchase space are blocked off with this... probably to make room for Joss preparations.
A large part of the GOTY section was replaced with a TV and a selection of GOTY movies as well.
All of this means only one thing: JOSS IS COMING!!!!
