An Elder Scrolls main-series game set in either Atmora or Yokuda certainly won't ever happen. You can easily eliminate those two as "candidates" right off the bat, considering that the main series is always going to move forward in time.

Even in terms of a side-game, Aldmeris can also be eliminated as a candidate (due to it being treated as the idea of unity among all Mer, as opposed to be a physical continent).

Pyandonea, Akavir, & Atmora are more likely candidates. Atmora however can only fit in a side-game, as it has been an inhospitable frozen-over wasteland since before the First Era.

Therefore: Pyandonea & Akavir, after Bethesda is "done" with Tamriel, are the ONLY likely candidates for exploration in future main-series TES games.
