They allready did the BWE and playable demo at gamescom would be the same area as during the closed beta. The waypoint, event and colours of the map fit the verdant brink map.
Arise, opressed of Tyria!
I’m pretty sure that’s verdant brink. Grune = green (i.e. verdant) and schewelle means something like threshold (i.e. brink).
Besides, we know we will not see anything besides Verdant Brink (and not even the entirety of that map) in betas:
we’ll only ever be showing the first story chapter and parts of the first map of the expansion during beta weekends to ensure that an entire world of discovery and excitement awaits you on launch day when you venture deeper into the jungle.
