Someone speculated Alexander seemed to be around Ewe Lake. From the looks of Heavens Ward we might be going around that mountain that is on the map with Ishgard. So West Highlands may be the access point to those other areas. Another theory to consider is other areas around Lower Coerthas, may have been renamed as part of a lager plot or with addition of entirely new areas outside the old zones. I think they did say the expansion's plot wasn't as big as ARR or others in development. So it might be a good way to add more new zones. I doubt Alex was in Ewe lake as in the video clip with the black Chocobo. It was flying by part of a large bubble with some suspended rocks on it. That area looks like it might be where that raid is. However Western Highlands was the only area old players seemed to recognize by name. I'd like to know if it was frozen in 1.0 as well. That will give the best idea of what they might be doing with the old areas that are missing.

West Shroud is MIA along with the central Low Lands. With Shiva freezing everything the Ixali there could be trying to relocate into the shroud. There's a good chance that in the future expansions we would get all the zones reworked and added back in some form or another. Until then we go to wait and see how the maps for the new areas fit in together.
