Sony is set to give its Tokyo Game Show keynote this evening at 6:30 PT, 9:30 ET—however, if you're going by Japan's time schedule, it's technically being held tomorrow morning on the 19th at 10:30 AM.
The keynote is titled "The World Created by PlayStation 4," which sounds a bit pretentious if you ask me—but let's be honest, no one really cares what I think... Moving on! The speakers in attendance will include none other than President of Sony Worldwide Studios, Shuhei Yoshida, SCE President and Group CEO, Andrew House, and SVP and Division President of Business, Masayasu Ito.
Sony plans to provide a "detailed specification of this latest system and its exclusive software titles" as well as showcase "the new gaming experience that can be realized with the Playstation 4 platform." As such, you'll want to keep it locked to GameRevolution for all the juicy updates.
