All three platform holders are ready for what they hope will be their biggest and most important E3s to-date.
Microsoft will go all-out to reveal games for Xbox One at the show, in a bid to answer criticism about its console's focus on non-games functionality. It won’t just be Xbox One on the show floor, however, with Xbox 360 also set to feature.
Sony, meanwhile, will reveal the look of PS4, show off new titles including Destiny, and reveal plans to revitalise sales of Vita.
Finally, Nintendo may not have a big press conference this year, but E3 2013 marks one of its most impressive console line-ups. A new 3D Mario game, Zelda: Wind Waker, Mario Kart and Smash Brothers are amongst the games set to be revealed.
Microsoft’s retail, sales and marketing director Jon Grimes said: “As a milestone year for the Xbox brand, we’re thrilled to reveal our gaming portfolio in LA next week. Gamers should expect to see a new generation of gaming experiences on Xbox One, as well as great content for Xbox 360."
"We're looking forward to revealing more on PlayStation 4, and giving gamers a taste of the incredible line up of software that our own, and third party development studios have been working on," said Sony UK boss Fergal Gara.
"With Beyond, Gran Turismo 6, Tearaway, Killzone Shadow Fall and Drive Club on the horizon, there's never been a better time to own or buy a PlayStation console and we look forward to welcoming everyone, whether that be in person or via live-stream, to our press conference and stand at E3."
And finally, Nintendo UK marketing boss Shelly Pearce added: “E3 this year is all about first hand gameplay for Nintendo and we're looking forward to giving people the chance to get hands on with our upcoming software titles.”
