Is that from the original game or Guild Wars 2? Either way it looked really cool!
There have been interviews in which the devs said that we might glimpse the Dominion of Winds, the tengu city in Tyria, but we won't be able to go in it, at launch atleast. But i am pretty sure we will have some sort of interaction with the tengu. They are pretty original for fantasy games, and are not just the token harpy race that every game ever made, ever, just has.
Dominion of Winds isn't too far away from Lion's Arch so I think we'll definitely be able to see it.
Not sure if we could enter it though.
Maybe we could interact with the traders on the outside.
