I'm glad there's a bit more information on this, but a couple things I'm wondering:
* Will be be able to have a room in each of the city-states or only in our starting city-state? I'm taking it as our starting city-state seeing how the quests required for completion are the main storyline quests before heading to Ul'dah.
* In the future might we be able to choose from a preset choices of layouts? While I know we can't customize it being able to decide from a couple different layouts that differ a little might give us at least a bit of customization.
* Can you interact with furniture? Sit on stools, or the bed? I'm aware in some of the main storyline quests where beds were available in a certain given area you could sit down upon them.
* Will a retainer bell be available in your private room for calling up your retainer?
* Can others visit your room via party invite? Meaning if I team up with a couple other players can we all relax in my room and just hang out.
I'm pretty eager to see what's in store for the private rooms and glad they're finally coming at last.
