The 40 games will be spread out across the PS3, PS4 and PSVita platforms.
One of the bigger criticisms of both Sony and Microsoft's reveal of their new game consoles was the distinct lack of actual games shown. Sony, at least, wants to use E3 to make up for this, and confirm to us that its consoles are first and foremost for playing videogames (something that I didn't think it would ever have to clarify), by showing off over 40 games for its PS3, PS4 and PSVita systems at the upcoming game show.
Sony's E3 lineup starts with its press conference on Monday, June 10th at 5:30pm Pacific/8:30pm Eastern, and will be followed up by three days of the "PlayStation LiveCast show" featuring gameplay demos and developer interviews for upcoming games.
Some of the games you can expect to see during the event are Beyond: Two Souls from Quantic Dream, Destiny from Bungie, DriveClub from Evolution Studios, The Evil Within from Tango GameWorks, Gran Turismo 6 from Polyphony Digital, inFAMOUS: Second Son from Sucker Punch Productions, Killzone: Shadow Fall and Killzone Mercenary from Guerrilla Games, The Last of Us from Naughty Dog, Tearaway from Media Molecule, and Wolfenstein: The New Order from MachineGames.
You'll be able to watch Sony's livestream of the event from its various website, as well as directly from your PS3 - look for the icon under your XMB's What's New section - or PSVita - via its Nico Nico app.
Lastly, Sony has invited the first 40 members of the public to arrive at Los Angeles Memorial Sports Arena on June 10th by 4pm a chance to leave the unwashed masses behind and sit in on its E3 press conference in person.
