Sony Playstation 3 - Sony officially unveiled the PS3 to the public on May 16, 2005 during an E3 conference. A functional version of the console was not present at E3 2005 nor the Tokyo Game Show in September 2005, although at both events demonstrations were held on devkits (e.g. Metal Gear Solid 4: Guns of the Patriots) and comparable PC hardware, and video footage based on the predicted PS3 specifications was also shown (e.g. Mobile Suit Gundam). It was not until E3 2006 that games were shown on actual PlayStation 3 systems. At E3 2005, Sony claimed the PlayStation 3 would have numerous input/output connections, such as dual HDMI and three Ethernet ports, which were later dropped. In preparation for launch, Sony demonstrated 27 playable PS3 titles during the Tokyo Game Show in September 2006 on final hardware.
