The Lego Mindstorm robotics kit that powered the whole thing was discontinued in 2022. Since they're no longer making the robotics kits they have nothing to donate to the competition (or run the competition on).
The LEGO Education version of MINDSTORMS Robot Inventor, SPIKE Prime, is still available and a new robot kit, Computer Science and AI, is being released this year. After next season, LEGO will be continuing on with their own K-8 robotics program (as will FIRST).
But you’re right in that they’ll have another new line—“Lego Education Computer Science & AI”, which is different in a way I don’t really understand and doesn’t fill me with a ton of confidence.
