At the following E3 2010, Microsoft used its press conference on June 13, 2010, to fully premiere the Kinect hardware, along with a performance by Cirque du Soleil. During the conference, Microsoft revealed the rebranding of Project Natal as "Kinect", which Xbox Live director Stephen Toulouse explained was a portmanteau of the words "kinetic" and "connection", key aspects of the Kinect initiative. Launch dates were also given, with the Kinect to arrive first in North America on November 4, 2010. Microsoft also introduced a revision of the Xbox 360 that was slimmer than the existing model, included a larger 250 GB hard drive, and had a Kinect-ready port: this unit later became known as the Xbox 360 S. In addition to hardware, Microsoft and several other game developers and publishers showed off Kinect-ready titles during the E3 2010 exhibition.
