In a nutshell, USB 3.0 promises the following:

Higher transfer rates (up to 5.2 Gbps) Increased maximum bus power and increased device current draw to better accommodate power-hungry devices New power management features Full-duplex data transfers and support for new transfer types New connectors and cables for higher speed data transfer...although they are backwards compatible with USB 2.0 devices and computers (more on this later)
