Sony has announced that they'll be holding their annual E3 press conference on June 10, 2013 at 6PM PT. Sony hasn't said anything beyond the date, but you can expect the conference to be livestreamed, as well as covered live right here on Destructoid.
Obviously they'll be talking about the PlayStation 4. Perhaps we'll get a look at the console at E3? And maybe even pricing details!
Microsoft's conference is set for 10AM the same day, while both Ubisoft and Electronic Arts will be hosting their own press respective conferences during the afternoon as well. As for Nintendo, remember, they're not hosting an E3 press conference this year and are likely focusing on doing a few Nintendo Direct presentations instead.
