I think this is more of an isolated incident rather than a common thing. I'm sure we'll see it sometimes, but it won't be common enough to get rid of the quest markers.
I believe in, and hope for, this being true.
It can be fun to drudge through the wilderness of a game, but I don't like having to constantly jump between the game screen and a damn journal to fumble through the pages to find the relevant journal entry to read some cryptic message that says "When you leave town going south, go over 2 bridges then take the road to the east and cross another bridge, then go north up a passage to find the entrance to the dungeon."
The magic "know-all' quest markers were much better than the navigation "system" of Morrowind.
Just sayin'.
