It also isn't necessary. The only devices that currently use USB that might be bandwidth starved are external hard drives, and you can fix that problem with eSATA. And when compared to LightPeak, it is decidely lame. LightPeak allows for enough bandwidth that a device could have but one connector aside from the power cable and could run mouse, keyboard, printer, scanner, external burner, external hard drive, external monitor, webcams.... tons of devices on just one connector, all running from one to the other in a daisy chain. It is set rumored to come out at around the same time, and is protocol agnostic. It could supercede USB 3.0 in my opinion, and for all i know, it might.
