>>53317278Yeah, historically Rayquaza is featured in raids very infrequently compared to other legendaries, and often only for a weekend or a few days rather than a full week.
I'm fairly certain that Tapu Bulu is featuring in raids from Wednesday with a shiny debut, but the March content hasn't been confirmed yet. That will probably come today or tomorrow.
The Pokémon Presents announcements in a couple of hours will probably include a surprise for Gimmighoul or something. They usually have some sort of surprise Go bonus or event.
