Princess Fairytale Hall

There's a new sign and pictures outside what is going to be the new Princess Fairytale Hall. The pictures left me with more questions than answers. I'm wondering about the following:
Will all five princesses be in there at once or will it be three that rotate?
Will there be one line for all of them or will they have their own lines?
Where's Rapunzel going?
Will Aladdin meet alone in Adventureland?
What will happen to Tiana's gazebo?

I guess I'll find out the answers to those questions when it opens in 2013.
