After previously saying it would go ahead with E3, the ESA on March 4 said it was "monitoring and evaluating the situation daily" after Los Angeles County and then the state of California declared a state of emergency.
Last year, more than 66,000 people attended E3.
Sony dropped out of E3 in January to give its upcoming PlayStation 5 the spotlight at another time and place. Microsoft, Nintendo, Ubisoft, Bethesda, Sega, Capcom, Square Enix, Take-Two and Bandai Namco were among the companies that had been scheduled to participate.
