<P> No official Wi - Fi or flash memory card readers were ever released by Sony for the 20 GB system, although Sony had plans to do so . As of September 2009, Sony had placed no further emphasis on these proposed add - ons . Nevertheless, as the model features four USB 2.0 ports, wireless networking and flash memory card support can already be obtained through the use of widely available external USB adapters and third - party PS3 - specific media hubs . </P> <P> It was rumored that the Cell processors in the third - generation PS3s (40 GB, 2008 80 GB (CECHL, CECHM, CECHK) and 160 GB) would move from a 90 nm process to the newer 65 nm process, which SCEI CEO Kaz Hirai later confirmed, and later to 45 nm . This change lowers the power consumption of the console and makes it less expensive to produce . </P> <P> The redesigned version of the PlayStation 3 (commonly referred to as the "PS3 Slim" and officially branded "PS3") features an upgradeable 120 GB, 160 GB, 250 GB or 320 GB hard drive and is 33% smaller, 36% lighter and consumes 34% (CECH - 20xx) or 45% (CECH - 21xx) less power than the previous model, or one third of the original PS3 model . The Cell microprocessor has moved to a 45 nm manufacturing process, which lets it run cooler and quieter than previous models, and the cooling system has been redesigned . The RSX moved to a 40 nm process in the latest revision . The PS3 slim also includes support for CEC (more commonly referred to by its manufacturer brandings of BraviaSync, VIERA Link, EasyLink etc .) which allows control of the console over HDMI by using the TV's remote control . The PS3 Slim no longer has the "main power" switch like the previous PS3 models, similar to redesigned slimline PlayStation 2 . Support for emulation to play PS2 titles is not present in the Slim version, however shortly after the release of the PS3 slim, Sony announced a new series of PS2 remasters called Classics HD as in PS2 and PSP titles remastered in HD for the PS3 with Trophies and sometimes PlayStation Move compatibility added . As of October 2011, PS2 classics are available for purchase in the PlayStation Store . </P> <P> The PS3 slim was officially released on September 1, 2009, in North America and Europe and on September 3, 2009, in Japan, Australia and New Zealand . However, some retailers such as Amazon.com, Best Buy and GameStop started to sell the PS3 slim on August 25, 2009 . The PS3 Slim sold in excess of a million units in its first 3 weeks on sale . A 250 GB Final Fantasy XIII - themed PS3 Slim, which was white in color with pink designs, was officially announced on September 24, 2009 at the Tokyo Game Show as part of a bundle in Japan for Final Fantasy XIII, it was initially revealed in U.S. Federal Communications Commission (FCC) filings as the PS3 CECH - 2000B . Sony Computer Entertainment Australia also announced later that day that it would be bringing the 250 GB PS3 slim to Australia which would be bundled with other games and will not feature the Final Fantasy XIII theme . Although no North American bundles have been announced for the 250 GB PS3 slim, it is sold as a stand - alone console in North America . </P>
