E3 is happening this year, but will be digital-only, according to a report
Last year was the first instance of E3 not taking place during its usual week of early June, where it was instead replaced by a months-long event called Summer Game Fest. It looks like COVID-19 will still impact the conference this year as well, but according to a report, the show must go on. VGC has reported that they've seen insider documents from the ESA, which include plans to take E3 2021 digital. This online event would supposedly last three days and would feature major keynote livestreams from publishers, an awards show, and a game preview night, with smaller conferences from other companies scattered throughout the schedule. The ESA also has plans to distribute game demos to press, so that they would be able to cover new launches and games just as they would during a normal E3 show. Meanwhile, Geoff Keighly's Summer Game Fest is also planned to return in 2021, and will likely compete against E3's all-digital showcase.
