It would be a very nice to have as well as being able to have a above your should perspective. Would really give the game a different immersion feeling. As you said like NWN. Not expecting it, perhaps modding? Maybe something later on added.
The game's artwork and especially gameplay isn't really designed for it, though. That's why there's a fixed camera angle - so the art designers could save time (and therefore money) by not prettying up different corners.
Yeah but the 360 camera fix shows it's not all smoke and mirrors, there is a 3d world here. Imo it doesn't have to be perfect. NWN's wasn't and I loved the close over the shoulder WASD controls. But hey I know when I'm asking for a bit too much. I dream.
I'm cool with top-down, but my fav is still Wizardry 8. To me just more immersive.
