An extremely cynical way to do it would be to release another of their D&D Beyond only monster collections with a further "evolved" set of stats and monster design guidelines and push it really hard. Let DMs pay to evaluate the testing.I'd LOVE to see some Monsters and more stuff from the DMG. Monsters of the Multiverse, I suspect, will be similar to what they have planned for Monsters, but I expect that they'll continue the steps forward that they took with that book and step forward once more. Will they need UA feedback to do that? I don't know, but I'd like for them to try!
Because it certainly wouldn't surprise me if we saw maybe only one or two more UAs and those quite limited in scope.
