The makers will provide whatever drivers are needed.  USB 2.0 (with 
compression) will handle stereo.  USB 3.0 will go a lot further.

Simple sampling (40,100 * 16 bits) = 641,600 bits per second.  (TOSLINK 
uses 20 bits/sample as does ADAT, however).

TB (1) could handle several hundreds of such channels without a blink - 
even if each channel was oversampled 10X higher than 40,100 Hz.

TOSLINK modulates at a respectable 10 MHz - but that would limit 
oversampling and number of channels.  Definitely not the future-path.

ADAT is better for such uses - but the bandwidth is only marginally 
higher than TOSLINK.

I don't know where pro audio is leaning - but I'd bet it would be easier 
for them to go to TB over the next few years than any other direction.
