Maybe at the Los Angeles Convention Centre? It's unclear as yet.
E3 will return for E3 2020 over 9-11 June 2020, its organisers today confirmed.
While we know when to expect E3 next year, we don’t officially know where to expect it; ever since 2017, ESA CEO Mike Gallagher has expressed his concerns with current venue, the Los Angeles Convention Centre. Things weren’t made any easier this year as a major power outage (admittedly, not the LACC’s fault) meant the facility went without power for a small portion of the convention.
There was a power surge at #E32019 while I was at 2K (affected all booths) and all the PCs running Borderlands 3 needed to be restarted. That's gotta be an E3 organiser's worst nightmare.
