I think Elon has already confirmed the camera at the top IS coming back, in a tweet yesterday. Personally, I usually keep it at the bottom but its always nice to have options. Features wise, I'd really like the music volume to change with speed so it quietens a bit when slowing for roundabouts, etc. Always had that as standard in all my BMs.
The update enabling the camera on top is indeed out now. One day we might even get V9.
