    Except that the MPEG-4 codec for QuickTime isn't available yet (although

it was demoed at NAB).

    As a long term strategy, I think Apple is looking at making QuickTime
into a superset of MPEG-4, so it'll handle all the features natively, and
those features it handles that aren't part of MPEG-4 it handles as an
extension, not as some completely different thing.

    At least that's my guess.
