The Electronic Entertainment Expo will continue to be hosted in Los Angeles for at least the next three years.
The Entertainment Software Association announced this week that it has reached an agreement with the city of Los Angeles that will keep the annual expo in LA. It was also announced that next year's E3 will run from June 11 to June 13.
The press release also noted that this commitment will help the city continue to plan and fund its future sports stadium/convention center, Farmer's Field. In fact, the ESA has even been involved in providing input for the design of the new stadium, which is set to debut in 2016, a year after the current agreement expires.
