Questions!

Hi!
I come from DnL forums, but as you can see, the stress beta (read open) will come in april or may, like a free trial for everyone. I receibed an e-mail from mutable realms, and they said the OB will start in december. I´d really like to play wish until DnL release.
First question, will really december be the date of open beta?

Second question, I´ve read that the world will be really big, very close to DnL one, so I want to know more about transportation. Will there be lots of rideable creatures, ships, and such? Will there be flying mounts?

Third question, there is looting in this game? It´s a free pvp, isn´t it? There are sieges, siege weapons, and big wars between players?

These are my questions. Forgive me, I don´t want to be lame, I´ve not read the faq, but in these games it´s hard to find the answer to your questions. :P
Anyone can help me?
