More dynamic range. (Movies in particular tend to make more use of this.
Ever notice how DVD's on a computer tend to sound quieter than most
other audio sources? The average volume is kept down to allow more room
for loud obnoxious dramatic orchestral hits during action scenes. ;)

More headroom to perform audio processing without loosing perceptible
aliasing artifacts.

And if you've got this kind of quality in the studio, why not pass it on
to the consumer?

Data storage is cheap these days.

But they *are* getting more for their money. Its for the most part
beyond the limits of human perception, but its there. ;)

Well you said yourself, 44.1khz 16bit is "Good Enough".

And its been pretty well proven already that encryption of media formats
is fundamentally flawed.

And 4gigs will be childs play within 5 years.

Personally, I'd rather see more bandwidth put into increasing framerate,
but thats just me.

24/30fps film/video is only just 'Good Enough' to trick the human eye
into seeing motion. There's far more room for improvement. Ever notice
how eerily smooth a 3D game looks running on a monitor doing 82hz-100hz,
assuming the game is that fast? ;)

Ever play a video in xanim with it set to play at monitor refresh?

Ever rendered a 60fps animation in a 3D program?

Douglas Trumbull considered using 60fps film for the 'VR' parts of the
movie 'Brainstorm', to give it that 'more real' quality. But dropped it
considering there was no way they'd get theaters to upgrade. ;P

One of these days I want to get a slow-motion camera to play with.
Muhaha...
