Never going to happen... And honestly I don't see the difference as there would only be a set amount of video plays just like most video games. So people would then be complaining that there player always does the same dunk or the rebounding all looks the same. And as previously said a game with that type of graphic would destroy the server and be very costly to create and maintain. Hence the price to play would go from free to alot!
Ideally the BB's develop a ball tracker in time to accomidate the play by play. That way we will be able to see a bit more about how the engine works :)
