Umm...for as long as I can remember (that's a while now) the Disney Princesses have always been the in-thing. Disney has always had the knack to make their IP's the current trend. That aside, my wife would agree a Belle and Beast playset would be awesome. To include Lumiere, Cogsworth and Gaston! <<would be cool<< Lumiere with his flame throwing candles, Cogs with ninja-star like gears and Gaston with...well...no one fights or has muscles as big as Gaston's!!
As for the doubts of Pocahontas...well a simple google search will reveal the necessary toughness that came with being a First Nations princess. Perhaps not as tough and with the notoriety that their male counterparts had...though they had to be tough. And as such, had to be rather skilled with tools and weapons. IMHO
