Update: Mugello and Sochi have been confirmed for the 2020 calendar. Very excited about Mugello being added, "meh" about Sochi considering how processional it usually is.

Still to be confirmed, but I've seen multiple sources report that Mugello and Portimao are set to be confirmed for the 2020 F1 calendar later this week. I do hope it's true, as this would be one of the coolest things to come out as a result of the pandemic.

EDIT: Looks like the Nurburgring, and Imola are set to join the calendar as well!
