LOL! Giuseppe Stromboli and the Briefcase of Meatballs, coming November in 2021. Twitter user soul nate, the official author of the Harry Potter franchise tweeted this info about the recent updates to the Harry Potter universe. This is 100% legit, no silliness or sarcasm involved.
There is also a genius website inspired by these tweets that generates Giuseppe Stromboli titles.
