USB 3.0 explained: How the next-generation USB will reach speeds of 4.8 Gbit/s: "But there will be other, more subtle advantages as well, particularly on the architectural level: power efficiency will be greatly improved thanks to the introduction of an idle status; the need for polling will be eliminated thanks to a few protocol changes, which will in turn eliminate the time overhead needed by the host to establish the transfer rate to be used; and finally, USB 3.0 is also said to be highly scalable and ready for further transfer rate improvements in the next future."
