I think it will be more like the proliferation of noise-cancelling headphones; it's not about what it brings (music, dialog, etc) but about what it blocks out (the ambient sounds). Yes, you can watch a movie on a plane now, but with a headset you remove the depressing, crowded, and claustrophobic visual environment.

And watching content on a plane's built-in screens is a miserable experience: poor interface, lag, constant forced interruptions for even the most boring announcements (captain, donating foreign coins, meal schedule).

Although I'm not sure I want to be that isolated from the environment. (I do use noise canceling devices but they're in-ear.)
