Xbox 360 "Pro" Model Never Existed – Slim & E Are The Revisions

There was never an "Xbox 360 Pro". Microsoft used different naming:

• Xbox 360 (Original / "Fat") – 2005: 20GB/60GB/120GB/250GB HDD (Removable). White. Ring of Light. High Failure (RRoD).
• Xbox 360 S (Slim) – 2010: 4GB (Internal Flash) / 250GB / 320GB HDD. Black. Smaller, Quieter, Built-in Wi-Fi (N), 5 USB, Optical Audio, Kinect Port. Most Reliable.
• Xbox 360 E – 2013: 4GB / 500GB. Matte Black. Xbox One styling. No Optical Audio. Same internals as S. Final revision.

Identifying Yours

• Fat: Curved top, Memory Unit slots (2), Chrome disc tray.
• Slim (S): Rectangular, Glossy/Black, Touch buttons, "Xbox 360" logo vertical.
• E: Rectangular, Matte, Horizontal logo, No Optical Port.

"Pro" might refer to Xbox 360 Elite (2007) (120GB HDD, HDMI, Black, Chrome trim) – a premium Fat model. Or confusion with Xbox One X / Series X "Pro" marketing.
