San Diego Mayor Kevin Faulconer announced at a press conference this morning that Comic-Con will remain in San Diego through 2021. Prior to this, in 2015, it was announced that Comic-Con would remain in San Diego through 2018.
You can watch the press conference in the video below, provided by the City of San Diego.
I was hoping to see a change in venue. Sdcc has outgrown this one.
Awesome
I would prefer that they move the convention to Los Angeles. LA is the center of entertainment and it would make more sense to have it there. It is also easier to travel to for those who will be attending.
