Some random observations:

- Granson (the Hume from the tank role quests) is present in the trailer.
- Garlean airships can be seen in what appears to be the upper levels of Goug, suggesting a followup to the Gabranth plot thread.
- Ryne is present alongside Cid on what appears to be the Source.
- The imagery of Hydaelyn looks to be rather creepy and sinister!
