From update last night the DATs were put into the game for the new expansion. After a look through some of them, there are new maps for these zones.
Miseraux Coast
Vunkerl Inlet
Attohtwa Chasm
Theres your new abyssea zones it looks like. I didnt think would use any zones from the past but guess that explains why WoTG is required.
Refreshing the PW model into abyssea mobs apparantly as well.
