USB3 was also supposed to have fiber components. Really hard to find references for this online since at CES 2008 they showed the connectors without any optical stuff, but I found this: http://www.theregister.co.uk/2007/09/19/idf_usb_3_announced/ http://www.theregister.co.uk/2007/09/19/idf_usb_3_announced/ Anyone know why they didn't end up going optical + copper for USB3?
