PS4 In 2010?

The Vice President of Technology Paul Holman (Sony Computer Entertainment Europe), states that “a PS4 will be launched by Sony but not until at least 2010.” He said that “Sony will introduce a series of firmware upgrades that will give the PS3 more media centre capability while allowing for the introduction of third party applications and hardware “Such as interactive controllers” similar to the Nintendo” Speaking to consumer site Gamespot, SCEA communications boss Dave Karraker said, "Following the launch of the PlayStation 3 just a few weeks ago, and witnessing the huge consumer demand for the product, I think it would be rather short-sighted for anyone to predict there might not be a next generation of PlayStation product."

Playstation 3 (PS 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 two HDMI and three Ethernet ports, which were later reduced to one of each.[10] In preparation for launch, Sony demonstrated 27 playable PS3 titles during the Tokyo Game Show in September 2006 on final hardware.

The basic configuration of the console has a 20 GB internal hard drive. The "premium" version of the PlayStation 3 comes with an internal 60 GB Serial ATA 2.5" hard drive, IEEE 802.11b/g Wi-Fi connectivity, and multiple flash memory card readers, and features a brighter silver-colored trim. Both consoles now feature a silver-colored logo. The hard drive is upgradeable, using the standard Serial ATA interface. Memory card support can be added to the basic configuration through adapters, but there is no official Wi-Fi adapter. However, as both models feature wired gigabit Ethernet capabilities, wireless networking could be added through the use of an external third-party wireless LAN adapter. Sony announced that the HDMI cable will not be included, instead Composite video cables will be included.
