As many others have pointed out to you, they've published several brand new settings: Ravnica, Theros, Strixhaven, and Wildmont. And they're going to be publishing new ones. Do you like any of them?
According to Amazon, Guildmaster's Guide to Ravnica is ranked #53 in D&D books and is #12,607 in books in general, Explorer's Guide to Wildemont is ranked #55 in D&D books and #13,258 in books in general (yes, a Critical Role setting is less popular than a MtG setting, according to Amazon). And Van Richten's Guide to Ravenloft is ranked #15 in D&D books and is ranked #1,901 in books in general. I think that's a pretty clear indication that people want new editions of older settings, not newer settings.
