Disney Princess new redesign in Disney site

I was opened official Disney site: link and found the Disney Princesses pages with new 2D redesigns, except Pocahontas.

But I wonder, why she doesn't got the new redesign artworks? Even the new Merida got one. I've often seen the illustrations for her is different from the others. As example: the 2012 redesigns. Pocahontas isn't get some sparkles and replaced by jewelries.

I couldn't understand why they're always design her illustrations was differently from the others.
