Well, from what I hear, it's a possibility. I was thinking the same as the No option (since she's a queen and she's a villain). But Disney might bend the rules and put her in anyway. And I welcome her if they do.

They say thet is not the villain , because she goes away of her home , because of her powers and hides in her ice castle and in the end becames good, also they say because she is Anna's sister she might be a princess, but I don't know..

Well, yeah, but they said that one of the reasons Meg from Hercules wasn't in the lineup is because she is kind of like a villain since she worked for Hades. So I assumed that in Frozen, Elsa will be attacking her own sister because the real villain is brainwashing her or something.

If Merida (the specifically made anti-princess) and Mulan (not royal in any way) can be princesses I see no dang reason why Elsa can't. she is a princess, but becomes queen.

I dont know about having her coronation that late though. but I guess it depends on when the movie comes out.

She will. Even now, before premiere, she is way more popular character than Anna. Elsa would give Disney money, so they would give her Disney Princess title.

Yes, now after Tiana, they want more princesses in the official line up, that's why they do all this will Elsa.

She may not be the true villain, but she still is a bad guy for probably most of her movie. I just can't see Disney doing it.

It's difficult to say. I personally really hope she is added to the lineup, because I can already tell that I'll like her way more than I'll like Anna.

The way Disney making every single girl who has the word princess in front of their name a DP yes she'll join.

It's already been confirmed that she will be joining the lineup with Anna in 2014.
