Sony Playstation 4 Commercial release date

 
 
While Sony has not released any official information concerning the system's future launch, the generally accepted release date is pegged as late 2012, which would follow the trend of Sony's previous console generations. The PlayStation 1 was first released in late 1994 in Japan and 1995 throughout the rest of the world. The PlayStation 2 hit stores in 2000, giving the PS1 a retail shelf life of 6 years from its Japanese launch. Likewise, the PlayStation 3 came out in 2006, 6 years after the release of the PS2. Following this trend that Sony has established would give us a late 2012 release for the PS4.
