The site is far better than the trailer, quite impressive actually (certainly compared to ARRs). I'd imagine the three other options will be something like;
-The new guilds.
-The personal islands thing they mentioned at the Vanafest.
-This expansions Campaign aspect (clearing the land, building camps and generally exploring).
I imagine almost everything currently on there will get updated at some point too, and they could also have another page hidden on the home page, like the not-so-varied personages page.
