I'm assuming most of the new MSQ dungeons will be on the First but the last one will likely be on the Source and tie into the next expansion somehow. I'm curious as to where they'll be since I haven't seen too many landmarks and locales that stand out as future dungeon material.

We're also likely to get "hard" versions of some of the Stormblood dungeons if they choose to follow tradition (I'm hoping for Bardam's Mettle as one of them).
