Will we ever revisit other "destroyed"/inaccessible areas from 1.0?

[Shurrikhan]

Pretty sure West Shroud still exists at least in part, because I recall an NPC mentioning something about a patrol or something that had been sent there.

But with Sorrel Havens (West part of Central) changed from a long, misty river into a dry well and Treespeak (East part of Northern) no longer having its second level of rope bridges and tree-clefts, I wonder just how much they can really do with it... Maybe we can at least see the SW parts like Turning Leaf returned in some (hopefully entertaining) style? (I really miss that base-camp of AF-questers just past the initial lvl 99 treents.)

Regarding Coerthas I recall a great deal of it was deep crevices in varying parts of the zone. So it could be that these particular areas may have caved in from the aftermath of the Calamity making the entire area inaccessible. The other thought is that we have no idea how far the wall of ice goes. They mention that there are countless caverns running through all of Coerthas so it may be that the entire half of the Lowlands are a huge chunk of ice and snow. The dungeon in Snowcloak may even be parts of the Lowlands still encased in a dome of ice.

Some other areas I missed in the initial post, now added to the OP:

Cassiopeia Hollow

A dungeon area near 1.0's Camp Bloodshore, presumably this would be somewhere near Costa del Sol now, but it's not really hinted at anywhere. I would imagine there would be little interest in reviving this area as Sastasha already covers what it might offer thematically? Still would be interesting to know what happened to it.

Shposhae

A dungeon area near 1.0's Moraby Bay, presumably this would be around where "Moraby Bay" (the bay itself rather than the drydocks) is marked on the map, but it's not really hinted at anywhere. I would imagine there would be little interest in reviving this area as Sastasha already covers what it might offer thematically? Still would be interesting to know what happened to it.
