Question regarding 9 new areas

[Zohar_Lahar]

Also, if Ishgard is only being considered as one zone that means

1) Ishgard (north of current coerthas zone)
2) Coerthas Western Highlands (West of current coerthas zone)
3) Sea of Clouds (above coerthas/ishgard)
4) Dravanian Forelands (West-west north of Coerthas Western Highlands)
5) Dravanian Hinterlands (North of Dravanian Forelands, also could contain the Farreach and Agalathia's(spelling?) Spine--basically the big mountain)
6) The Churning Mists (area directly north of Ishgard? Or after watching the exploring heavensward video another time, Churning mists looks like it could be the remains of Sharlayan, and they might be pulling an effect similar to Riverne Site A and B where some super weapon has altered the gravitational pull of the area, sending it into the sky in fragments--as the location looks like a bunch of destroyed building bits and there is even a massive ominous storm cloud thing in the distance, which could be where the Floating Continent is in)

Abalthia's Spine is the name of the entire mountain range, not just that weird mountain with a floating peak. As for Churning Mists though, going by your theory, could it be the remains of the Isle of Val?

The churning mist is the part of the sea of clouds in dravania, in Japanese it's name is dravanian sea of cloud.

It can't be the isle of Val imo, it has been engulfed in the void, its unlikely it would reappear there. ( unless someone used another dimension )
