6.0 Predictions: Will it be Garlemald, Sharlayan, or Meracydia?

[RyuDragnier]

Anyway, as to the thread, it's Garlemald confirmed. Assets and art for a Garlean aetheryte were recently datamined.

All that confirms is that there's at least 1 zone in Garlemald. It does not confirm that the entire expansion will be there.
