Here's what it looked like during the PoF betas:
Basically a pair of small reed boats in the river mouth, with all the standard services close together.
It's massive and much more ornate and open, but also more spread out. The crafting stations are on the upper level (reached by using teleporters) and the Mystic Forge is on it's own platform off to one side. Other services are in a large ring around the outside.
Whilst I'm aware this is what many players asked for - especially to have more space and higher ceilings - I have to admit I'm slightly disappointed. Don't get me wrong, it looks very cool, but one thing I liked about the original version was that all the services were very close together - within a few steps of each other. Which IMO is ideal for a quick access mini-town. If you want to drop things off or pick things up or whatever you go there, if you want to hang around you use the pass then go into Amnoon or go to LA or any city of your choice.
I can't complain since when I bought the Ultimate edition I had no idea what this area would look like, and I'd actually decided I'd buy the (IMO inevitable) PoF pass anyway to act as a cheap, easy way to reach the desert maps. It just came as a shock after getting used to the idea of this little river boat with all the services close together.
"You can run like a river, Till you end up in the sea,
And you run till night is black, And keep on going in your dreams,
And you know all the long while, It's the journey that you seek,
It's the miles of moving forward, With the wind beneath your wings."
