Quite a few companies are doing it now due to the cabin isolation. Door seals are so effective that you can't hear any engine noise. BMW just chose to augment via the sound system instead of running a tube from the intake into the cabin.
All these cars have this feature on them : VW GTI, Ford Mustang, Mini Cooper S
Not saying I disagree with your argument, but you might find it is difficult to find a car of the M3's quality without that feature within the next couple of years, if they do choose go to that route.
