I haven't loved everything WotC has put out in the 5E era, by any means (most of my D&D book shelf is third party stuff), but aren't Journeys Through the Radiant Citadel, Wild Beyond the Witchlight, The Book of Many Things, Keys from the Golden Vault and Dragon Delves "new?"Most of these suggestions are for WotC to bring back something old. That old stuff already exists, and can be readily adapted if desired. I don't think I've been excited by anything WotC has produced since Eberron, and I would have been excited for a Nentir Vale setting. I kind of want them to do something new.
Not that I believe that they're currently capable of making something new that I'd be excited about. But I'd still prefer them to try rather than warm up the leftovers.
Or are you looking for something more radically different?
