When the Wii U was released at the end of last year, Nintendo got a head-start on the long-awaited new generation of video game consoles. Now, Sony has announced a press conference for February 20th that is expected to unveil the PlayStation 4, codenamed 'Orbis.' This will precede the announcement of the Xbox 360's successor, codenamed 'Durango,' but that too will likely be announced by E3 in June. Specs for development kits of both systems have leaked widely. The two systems both use 8-core AMD chips clocked around 1.6 GHz. Durango has 8GB of DDR3 RAM, while Orbis has 4GB of GDDR5 RAM, though Sony is trying to push that up to 8GB for the console's final spec. Reports also suggest Sony is tinkering with its controller design, going so far as to add a "Share" button to let people exchange screenshots and recordings. Developers indicate the systems are very close in power, though Sony's system currently has an edge. With the upcoming announcement of the PS4, the big-three console makers will kick off a new round of direct competition. They'll maneuver to one-up each other with the most powerful hardware and the slickest software. However, they'll also hope the release of three major consoles in rapid succession will help to anchor a part of the games industry that no longer enjoys the dominance it once did, thanks to threats from mobile.
