I want a video of a 3DS running the title screen for Sun & Moon. The evolution music will start to play and the 3DS will begin spinning. The screen flashes white, and then it's revealed that the 3DS has evolved into a Switch playing Pokémon Stars.
I think they'll reveal it in the middle of a presentation about Pokken Tournament DX for the Nintendo Switch. This presentation will be part of a special Pokemon themed Nintendo Direct first announced a few days before it airs.
Oh wait, never mind.
