It's my understanding that with 2.0, the cities themselves aren't changing much. The one thing I would request or at least hope they consider changing, is the Aetheryte Plazas.

Everyone has seen the original 1.0 trailer, where the trio of Elezen, Miqo'te and Hyur were in what appeared to be the adventurer's guild getting some levequests. In the center of this area was a large crystal, reminiscent of our current Aetheryte.

I would like to see the city Aetherytes moved to make such a location. Currently they are tucked away into a corner of each city. Not really a centralized location. I'm not saying put them in the Adventurer's Guild, but take Ul'dah for example:

The current Aetheryte is on the edgewall of the city. The middle of the city would make a fabulous place for the crystal, and it could even be increased in size. Don't get me wrong, the fountain is neat and all, but the Aetheryte would fit so much better there. It's a central location in the city.

If the Aetheryte Plazas could be something more than they are now, like a centralized hub for people to gather at, I think that would really add to the feel of the game.

Just a thought, considering 2.0 will allow more than 40 characters to be loaded onscreen.
