Light Peak and USB 3.0

Light Peak is the name of the new Intel optical interconnect for computers and consumer devices.  Using thin optical cable, Light Peak will begin at a speed of 10 Gbps, and move to 100 Gbps.   In comparison, the newly emerging USB 3.0 reaches a theoretical maximum of 3.2 Gbps.

Out of the gates, USB 3.0 has the advantage of backward compatability of a huge installed base.  But it is also a technology that has passed the middle age of its lifecycle. 

There is considerable speculation that Apple will bypass USB 3.0 in favor of Light Peak (e.g., here and  here).

I imagine that along with a copper pair for power, and the long cable lengths allowed by Light Peak, we may be closer to my longstanding wish for a daisy chain of my audio, video and computer components, replacing the current dense mess of cables.
