First appearing at CES 2008, the RAVEN looks like it should be on many gamers' shortlists. Having the ability to fine tune and customize every mouse movement is a start, add a lightning fast mouse sensor capable of 3200dpi and we may have the complete package we have been waiting for. The RAVEN can handle up to 50G of acceleration, and allows for independent X and Y axis dpi adjustments, perfect for fine tuning to match users' preference.
