Editing PlayStation 4 (section)

==History==
While much of its development on the new console was talked about as early as of the late 2000s, Sony was trying to avoid the same mistakes that they made with their [[PlayStation 3]]. The PlayStation 4 was unveiled on 20 January 2013 though most things such as the hardware, controllers, and others were explained. The design was not unveiled until the E3 on June 2013. The PlayStation 4 did have some major reputation, much of which had called an improvement since its PlayStation 3 days, including the lack of digital-rights management restrictions (much of which was implemented by Microsoft on its Xbox One though removed after the E3), the allowance of self-published titles, and among others. The PlayStation 4 was released on 15 November 2013 in North America, eventually breaking the record as the fastest selling console in history with one million units sold in under a day (though the Xbox One did the same a week later on its 22 November launch at thirteen countries). The PS4 was later sold in Latin America and in Europe on 29 November and later sold to other countries within the holiday season of 2013 on towards Japan's launch on 22 February 2014. Currently the PS4 has one of the most units sold as an eighth generation console at 50 million units as of December 2016.

On September 2016, Sony unveiled two new revisions of the PS4 consoles. The first, model number CUH-2000 (unofficially referred to as the '''PS4 Slim''') is a revision of the original PS4 hardware with a smaller form factor; it has a rounded body with a matte finish on the top of the console rather than a two-tone finish, and is 40% smaller in size than the original model. The two USB ports on the front have a larger gap between them, and the optical audio port was removed console and was released later during the same month. The second is the '''PS4 Pro''' (codenamed Neo), model number CUH-7000, is an upgraded version of the console designed to support [[Wikipedia:4K resolution|4K]] rendering, including an upgraded GPU with 4.2 teraflops of processing power, and a higher CPU clock. Games can be optimized for higher graphics quality and 4K support when running on PS4 Pro. The PS4 Pro was released on November 2016.
