Personally, I truuuly hope they don't, or at least add some kind of option so that we that don't like them, easily can turn them off.
In Oblivion, quest markers made me feel like a robot. I wasn't doing a quest by myself, I was just following a red spot on the map, killed or grabbed the red spot, then followed another red spot.
Please, let me think some on my own! Remove the Oblivion-featured quest markers completely, or change them completely, or make it completely customizable!
In return, give more/better directions, so that you can find anyway, but on your own! Kind of like Morrowind, hurray! :celebrate:
