Self explanatory really, will we ever see one? Should we? Or should it be left up to our imagination?

We have one of the remnant isles of Yokuda, Akavir wouldn't make sense in a lore-themed one since it's never been mapped out by Tamrielites, Atmora is too frozen to do a complete map and Aldmeris doesn't exist.

If they do a non-lore one I feel that would be incredibly boring as it's just "here is a map" but with one that is based on lore as in made by someone in the universe that would be a thousand times more interesting as well as it having a story.

There's a map of the Yokudan Isles? I've never seen that. We could see a theorised in-game map of Akavir though, maybe one that's not completely accurate, unless that already exists as well. Maybe a game with a story involving Akavir (I don't think we'll ever go there) could lead to a map drawn by the Akaviri.

There's also Pyandonea.

since they had mananauts go to the moon and back, you'd think there would be a full map somewhere. maybe even the dwemer had one at some point.

The Synod could wind up with a full map. They already were off to a good start in the CoW questline.
