I've been waiting for Terri Gold to post a link to her beautiful 2010 IDEX pictures. She has done so. I had to stop working to take a cursory view. I'll view the over 200 images later today.
From what I've seen thus far, Tonner is offering princess dolls... is the dark-skinned one Princess Tiana? Probably. Jason Wu definitely has two Princess Tiana offerings.
Again, I'll study the other images later.
