I doubt the isometric view is going away, and a lot of us don't want it to go away. And to be honest, games like Dragon Age: Origins would have been great candidates to have an isometric camera view. The camera in DA:O was quite awful, and even in DA:I it's still pretty awful. I'm not sure how you imagine 'looking at the entire battle area' since having an isometric view is pretty much the only way that you can view the entire battle area, the only other view would be if it was top down.
But in the enhanced edition you'll be getting 360 degree rotation of the camera, maybe that will help you.
