So when do you guys believe we are gonna get an trailer for the Sun and Moon anime?
For me personally, I think it's gonna be during the 1 hr special on September 15th.
Aside from wanting Serena to travel with Ash to Alola, my second wish is for the writers of XY & XYZ to continue being in charge of the story for the Sun and Moon, and only them. Not the B&W writers ugh.. the fact they wrote the Kalos league finale was unbelievable.
As for Ash's Alola traveling Companion.
1. Serena (A guy can dream lol)

2. Lillie

Between the two female protagonists in Sun and Moon, Lillie looks more interesting.
3. Hau

Kinda reminds me of Sawyer (Shouta), but he'd be a cool addition to the group.
On a little side note, I saw this and went this would be a great interaction:
