According to the GeekMom.com website, Disney has decided to stop making movies that feature princesses. This isn't some kind of attempt at appearing as a modern, pro-feminist cartoon-making industry-leader giving young girls more realistic role models. Nope. It's because boys don't give a rat's ass about princesses. From the website:

The actual statement made by Disney executives says fairy tale movies, but since the majority of Disney's fairy tale movies have revolved around princesses, it means practically the same thing. Especially when you read further and learn the reason they are putting princesses aside: Boys won't see movies with icky girls in them, and Disney does not want to risk alienating any boys.
