When trailer creators make something, they make it with the intent to show off the game as best as they possibly could. Which requires confidence in the game's current state and set-pieces.
If they showed this off, that means they're confident about the game looking good. Trailers are meant to sell you on the game as best as they can.
Just look at Sonic 06's E3 trailers. The game unironically looked great from a gameplay standpoint, but we all know how that fucking went. Notice how there isn't much change from it and the final game.

https://www.youtube.com/watch?v=T1aUnSyd4r4Like I said, we haven't seen much of anything change from Pokemon's trailers, just more features that WILL be thrown away for the next games. And it's always been that way for a really long time, even during BW1's initial reveal (with the biggest difference with that literally being Excadrill having a purple-hue and the markings being reversed on their stomach).
If GameFreak shows off differences between trailers you can argue this, but for now, you have no hill to die on besides blind ignorance.
