 It's Wednesday, February 20th, 2013. I'm Ross Miller. And I'm Chris Grant, editor-in-chief of Polygon, and this is 90 Seconds on the Verge, brought to you by Motorola. Ending weeks of rampant rumors, whispers, and other rabble-rousing, Sony has announced the PlayStation 4. The hardware is based on, quote, Supercharged PC architecture with eight CPU cores. Yes, the graphics are better. The new DualShock 4 controller has a touchpad, headphone jack, and share button. Sony says its goals make video sharing as popular in PS4 as screenshots are today. There's also a new 3D camera that's not entirely dissimilar to the Microsoft Kinect. Sony's really big new feature is game streaming using clouds. PlayStation 4 games can be played in full while they are being downloaded, streamed in a similar manner to how Netflix streams movies. You can also use the PS4 as a server and play the games using the PS Vita, kind of like the Wii U. The technology is being provided by Gaikai, which Sony purchased last July. Here's the catch, though. PlayStation 1, 2, and 3 games cannot be played natively. Sorry, cloud only. Finally, something not at all related to Sony, Google Glass. The company today posted a video preview of its forthcoming wearable headset. Based on the demo, Google Glass will allow users to receive and execute on-screen directions, send voice-controlled messages, and search the web through speech. The key phrase is, OK Glass. Google is also expanding its pre-orders to, quote, Creative individuals, so beg them to take your money a little more creatively. OK Glass. And that's it for today's top stories. Coming up tomorrow, mathematicians have discovered the last digit of pi. Spoiler, it's 3.
