The initial reveal trailer is similar to SV's. Various shots of the region and different Pokemon, then the professor sends out the starters.

I cannot divulge any information regarding new Pokemon, but I've created a documentation with the new Pokemon blanked out, though I left the types intact.
There's a total of 103 new Pokemon, and yes the legendaries are both normal type, I believe they can change forms.

I won't share too much regarding the story but I get the feeling you'll all really like the new evil team, it's about time we got an actual irredeemable villain.

The Rotom Scooter you've all seen is identical in the latest build I've seen, and I imagine it'll stay the same in release, the only notable difference is you can ride the Rotom Scooter without being pulled by a Pokemon, though it's a little bit slower and you can only travel on land.

Feel free to ask questions, I'll answer all that I can.
