At E3 2006, Sony announced that the boomerang design had been replaced by the Sixaxis; a wireless, motion sensitive controller, similar in overall design to the earlier PlayStation DualShock controllers. The controller was bundled with all new systems from launch, until the introduction of the 80 GB (CECHKxx, CECHLxx & CECHMxx) model, which substituted the Sixaxis with the new DualShock 3 which added a vibration feature while retaining the design, features and functionality of the Sixaxis. The Sixaxis controller was later phased out and replaced by the DualShock 3 controller completely and is no longer being produced in any region.
