The Xbox 360 Premium model launched in the United States in 2005 with a price of $399.99.
Microsoft positioned the Premium package as the fuller launch option, including a detachable hard drive, wireless controller, headset, and other accessories. A cheaper Core model launched alongside it at $299.99, but it lacked several Premium features.
The price is sometimes confused with the Xbox 360 Core model’s launch price or with later price reductions. The Xbox 360 launched in North America on November 22, 2005, before arriving in Europe and Japan. Its early pricing reflected the console’s new high-definition output and online-focused design.
Later Xbox 360 revisions changed the hardware, packaging, storage, and pricing, so the $399.99 figure specifically refers to the original Premium launch package rather than every Premium-branded console sold during the generation.
