I've seen numerous mentions of the rescheduled London shows today.
But I haven't seen anyone mentioned the new US show added.
Brooklyn, NY - Barclays Center - December 11, 2021
(presale now with pw: DOMINO)
"Fourth and FINAL NYC area show"
Anyway, this is good news for the US tour because that obviously means they're confident that it will still go ahead as planned. Otherwise, they wouldn't add this right now.
(I've been waiting for updates on the US tour, so I can book my travel plans for Philadelphia. I guess it's "safe" now to do it...)
