I think they do go with their gut and will make the game as good as it possibly can be. Just because the game they envisioned did not spring from their minds fully formed exactly how they first dreamed it up does not mean they are not sticking to their vision. They have to ballance what they want to do with what they can accutaly sell. They could go hardline and say no levels. The game would be just as good for the open mined but large numbers of people would just go into shock and put the game down because its too forign. If they ease folks into the concept of levels not mattering or not really needing a quest giver they can ween the masses off that concept. If they go hardline the masses will rebel and only us diehard fans will buy the game and it wont be as sucessful as it could be.
