You make a good point. Since USB 1.0 ports and USB 2.0 ports have different colored jacks (black vs. blue), I'm not sure what USB 3.0 would do to differentiate itself. I don't have any USB 3.0 compatible peripherals, or built-in support on any of my pc's. So it's not like I've lost anything if they decide to change the standard. I would assume most people are like me and only have 1.0 and 2.0 support on their computers, so it's not like much is lost by improving their standard.
