Just a few things I hope will happen in the upcoming 4th season of Beyblade Burst
1. Bring back some of the old cast (Daigo, Ken, Wakiya, Rantaro, etc.)
2. Give the Snake Pit a proper origin story and tie up loose ends.
3. Have Lui return (He only showed up for the Luinor Cup arc, and just vanished afterwards)
4. Free and Shu returning with a new Gatinko Fafnir and Spriggan, respectively.
