IMHO TB will only make inroads in the pro-video sector, to provide peripherals for the new MacPro, which is a machine designed to do just that and not audio (and it would be foolish to pay through the nose for monster dual GPU’s that you will never need, unless you’re a video editor.) In the world of audio, it’s not going to make any significant dent. Heck, not even USB 3.0 will, because for 99% of the people, modern USB 2.0 interfaces are well capable to handle everything they throw at them.
