The previous launch trailers did have scenes from all of the MSQ dungeons IIRC.
I'm leaning towards the crystalline place being the Labyrinthos dungeon as given its location deep beneath the ground coupled with the Sharlayans actively researching the aetherial sea I feel like they'd have to have another Antitower-like structure to observe/access it from.
I'm assuming that dungeon with the portals is the one for the seemingly Ancient-focused mystery zone as the architecture is the same as we've seen from Akademia/Anamnesis Aynder.
That outdoor area with Garlean architecture seems like a distinct dungeon from the imperial palace/central tower and might be one of the post MSQ dungeons, especially since the Scions aren't present just for that one in particular. Perhaps there will still be some Anima-tempered Garleans lingering about that will need to be dealt with...?
That leaves the creepy hellscape as a toss-up between either Mare Lamantorum or the final zone...which has interesting implications in either case.
