'Evolution of PlayStation' Foretells A PS4 Announcement Feb 20

Sony posted a series of videos on its YouTube channel during the past few days called "Evolution of PlayStation," looking back at the history of PlayStation and highlighting each console's impact on the gaming industry.

Every day Since Feb. 15, Sony has displayed a video showcasing a PlayStation console and its place in the lives of gamers. It's hard to take this walk down memory lane with Playstation and not conclude that the rumored PlayStation 4 announcement at the Sony event Feb. 20 is definitely happening.

Evolution of PlayStation video lineup prediction:

Feb. 15 - PlayStation

Feb. 16 - PlayStation 2

Feb. 17 - PlayStation 3

Feb. 18 - PlayStation Portable

Feb. 19 - PlayStation Vita

Feb. 20 - PlayStation 4

We firmly believe today Sony will highlight the PlayStation Portable; if not, we'll go skinny dipping in an ice-cold river. Seriously, we'll do it, but first, we will have to be wrong.
