New Disney princess

Most of us love Disney animated movies and have at least one (if not few) favorite disney movie. Every disney hero/heroine has something special about him/her which makes us love the character. These years Disney is mostly doing new kind of princes/princesses who are pretty interesting and more realistic, but still have the magical/fantasy aura around them. But lets get to the point. Watching disney movies I noticed one thing and that is that Disney took almost every country and continent for location/settings of the story...except Slavic country (Russia, Poland, Macedonia...) and Israel. Why? Do you guys believe that there is a chance for Disney to pick some Slavic contry and/or Israel as location for some of future animated movies? What do you think about this? Could we have Jewish or Slavic prince/princess? 

Please, tell me your opinions.
