Sony teases PlayStation 4 reveal with Evolution video

Sony has updated its site for PlayStation Meeting 2013--the February 20 New York event where the company is widely expected to formally announce the PlayStation 4--with a new video, titled PlayStation Evolution.

The two-and-a-half minute video potentially teases a new hardware announcement on February 20 by detailing the launch of the original PlayStation in 1995 and the introduction of the first DualShock controller in 1997, alongside notable titles like Crash Bandicoot, PaRappa the Rapper, and Gran Turismo.

"Recognising the power of the Electronic Entertainment Expo, or E3, Sony Computer Entertainment's marketing machine hit the event full force in 1995, with an aggressive marketing campaign revolving around the phrase 'You are Not Ready' in an attempt to turn the PlayStation into less of a product and more of a lifestyle," recounts the trailer.

Two different photographs of the PlayStation 4's devkit controller have surfaced in the past 24 hours, showing a front-facing touch screen, integrated speaker, headphone jack, and an illuminating light that suggests some sort of PlayStation Move integration.

The last few weeks has also seen numerous reported specification sheets for the PlayStation 4 made available online. Various rumours have said the device with have multi-user logins and will be focused more on new ways to play rather than technical power.

Sony's PlayStation Meeting will take place in New York on February 20 at 18:00 EST/15:00 PST/23:00 GMT. GameSpot will be in attendance and broadcasting the event live.
