Hardware, Embedded Systems Intel and others plan to release a new version of the ubiquitous Universal Serial Bus technology in the first half of 2008, a revamp the chip maker said will make data transfer rates more than 10 times as fast by adding fiber-optic links alongside the traditional copper wires. Intel is working with fellow USB 3.0 Promoters Group members Microsoft, Hewlett-Packard, Texas Instruments, NEC and NXP Semiconductors to release the USB 3.0 specification in the first half of 2008, said Pat Gelsinger, general manager of Intel's Digital Enterprise Group, in a speech here at the Intel Developer Forum.

why would you think that the cable is not going to be backwards compatible? They are ADDING an optical link not replacing the coper wires with optical. Just like you need a shielded cable in order to run at usb 2.0 speeds and you don't need shielding for a low speed usb cable you will have an ultra high speed cable that has an optical channel in order to achieve the really high speeds. The jack is exactly the same the protocol is pretty much the same and there is no problem using the new cables with older devices or new devices with older cables as long as you don't mind the reduction in speed. In every respect this IS a usb revision. The big problem however is that there is quite a bit of overhead on most usb drivers that exist today. There will have to be some better quality control on those in order to reach the promised speeds. But then again there are hardly any usb 2.0 devices that perform up to the standard ...

Truth be told I really don't know of any device on the market today that can benefit from a usb 3.0 connection. Sure it allows for more power to be drawn and has higher promised throughput but you can get high speed with eSATA and a lot of power and reasonable speed with firewire800. Yes firewire 800 seems to be an apple exclusive ( almost ) but this is mostly due to the fact that there is no consumer interest in firewire products when it comes to the windows world. That still doesn't mean that the technology does not exist or that you need to create a super expensive optical hybrid cable for the next revision of usb. Oh and whatever happened to wireless usb?
