The most concrete part I get is that it has a recognition and positioning system built-in, so it can recognize the IDs and relative positions of nearby beacons. Beacons are inside bricks, tags and minifigures. The bricks seem to also have some kind of color sensor to detect the color of nearby normal bricks.

Then it does ... something with that information.

From the promo it almost looked as if that data was fed to an LLM that could then generate an audio response that fits to the play scene. Something like "You are a <Lego Star Wars minifigure>. You are <sitting> in a <vehicle: air plane>. The vehicle is <turning along the Z axis>. What do you say?" (Where the stuff inside the brackets is inferred from the nearby beacons and the rest would be a fixed prompt template)

But that would require the bricks to have an internet connection, and I have no idea if that's the case.
