Sony's E3 2015 media briefing will be held on Monday evening, on June 15 at 6pm PT.
The home of PlayStation confirmed its press conference plans in an invite, which is currently being sent out to members of the media (thanks, GameSpot).
Sony also has a number of other first-party content that has yet to be announced. What's Guerrilla Games working on? How about Sony Bend and Santa Monica Studios? Is there a shred of hope that The Last Guardian makes an appearance?
