The video doesn’t say much; but it’s clearly PlayStation.
The US PlayStation site has a sign up page that offers to let you be the first to know. It also clarifies the exact time of the news; Februrary 20th, 2013, 6pm EST.
It may well be the PlayStation 4. Of course, it could be a new cloud or network service. It might even be a Kinect rival. However, this blogger is betting that most people are now expecting the PS4 news to appear in less than three weeks.
