If I'm not mistaken, the emerging hi-def audio standards (DVD-Audio and
SACD) use 96kHz.
Now, these are very young standards, barely gearing up to gain market
share. It's gonna take time until they will be replaced by something
using a higher frequency.

Well, they're full fledged professions after all. I'm not saying it's
impossible to be good at writing music, AND playing it, AND mixing it,
AND mastering. After all, music giants such as Vangelis did it
successfully, at least in some instances.
I'm just saying that it's a rather uncommon achievement, despite the
common perception.

Good luck, go ahead and try it. You might just have what it takes, but
you'll never know unless you actually try.

Do the math. 32 bit is beyond the level of quantum fluctuations at any
reasonable temperature. All it takes is a single analog link in the
chain and poof! there goes your 32bit depth.
Even 24bit is overkill, but it's just the right amount of overkill. ;-)
