It looks like San Diego Comic Con will once again be virtual, with the event being held from July 23-25. They hopefully plan to have large, in person conventions in 2022, but it seems like a smaller venue will be held in November. In addition, Wonder Con will be virtual again, and be held from March 26-27.
