Edit: by the way, that tweet only has 30 likes! Are PFH announcements always this subdued?
It's not an announcement from the proper Larian/BG3 twitter account, but a small tease posted by a single developer from his personal one.
In terms of public reach is basically the difference between, say, "Elon Musk said X on Twitter" and "One friend of mine that works at Tesla said he heard a rumor".
