Think there's anything to the "...It all comes together..." statement made in the trailer? Maybe that lovely mansion they're showing is a tournament battleground sorta thing akin to PWT in BW2 where you fight the leaders/champions from all over the world.
Also, they should have definitely thrown some celebrities like RDJ, Ronda Rousey, and Weird Al in there instead of just random ethnic nobodies and white kids. Have fond memories of the ad campaign with Robin Williams and his daughter Zelda for the 3DS OoT release, hell he even wanted to play Professor Oak if they ever did a live adaptation. Too bad celebrities cost money.
