Seems that Thunderbolt is finally accessible to PC users now and I'm wondering if Thunderbolt will be the replacement for USB?  Thunderbolt itself delivers 10W of power, so would that also mean that products like the audio-gd DI and the Audiophilleo (Thunderbolt successors) would not require dedicated PSUs for best performance?  Just from reading a couple articles, this seems like a much better technology than USB since USB has so many inherent problems for audio.

I don't think we'll be seeing it anytime soon. It's barely even taken off for external HDDs, and I think USB 3.0 has a better chance of making it. 
 
Switching a completely non-backwards compatible format is always a tough sell.
