here, here and here.
Integrity has confirmed that the upcoming "Hit Single" Darla, which was shown in promo pics with the original face, will indeed have the new sculpt and not the sculpt shown in the promos.
The other news was the introduction of a new, closed-mouthed sculpt for the Fashion Royalty line's Adele character. The new sculpt is LOVELY. I don't currently own the new sculpt (yet), but I'll link to a few pics here, here and here. This sculpt change follows the revamps for the Fashion Royalty Veronique and Vanessa characters. From what I understand, molds get old after a certain number of uses and start to lose their fine detail. Integrity fans expect that Kyori will be the next to get a facelift; I can't wait to see what's in store.
Below is the last Adele made with the open-mouthed mold, 2011's "High Brow" Adele.
