There a few remnants that we can pick up from the trailer, it's mainly just Artwork. There's a pickup truck with a Machoke riding on the back, as well as 2 other Pokemon that I can't identify. Meanwhile a Blastoise is riding on the back of what looks like a make-shift firetruck. An Ambulance? Seems to be a focus on featuring vehicles this time around. A selection of designs for the interior of the Pokemon Center.
A building that looks like it could be a Water Gym, it features a fountain and some palm trees. Perhaps the new region is a more tropical region which on board with. You can see artwork of Wingull in the bottom right corner of one of the shots which might point towards that theory of being close to the sea, a real summery vibe.
Edit: That might be our Male Trainer outside the gym, clad in a Red and Black hat and jacket with Blue Trousers, looks pretty standard right now, I sure hope the trainer customization makes a comeback.
Then there's that last part animating they Wireframe of that one Pokemon, no much to say other than we have our new Pidgey/Pidove/Taillow.
