The trouble with judging the swing via the ani is that the swing plane isn't animated. I don't see that happening for a long time.
I think Joe has the key to swinging while watching the curser. Your peripheral vision will give you quite a good indication of how much backswing you have taken. The curser path can be positioned to give you the best peripheral view of the backswing and I'm sure it will become a natural action after plenty of practice.
As for immersion, I'm keen on using the F5 function to position the camera above the ball from a real life perspective and use muscle memory to determine the backswing length together with the view of the curser on the screen. I'm not that keen on watching an animation of a golfer. It remains to be seen whether this would be successful but it would be amazing if it was and would place even more emphasis on 'feel'. (I would be happy to have an option to turn off the golfer in the normal MS swing.)
It will be hard to maintain the preferred swing path without the guide of the gauge (6 to 12 o'clock) but I'm sure people will come up with measures to assist with that. Don't forget - the animation doesn't show the swing path.
Exciting times and these are stepping stones to Perfection.
