Watch part 3 of the Pokémon Sun and Moon 'Train On' trailer

Yeah, this kind of eludes to the idea we can travel back to Kanto, as that's where we are originally from in this generation. I have faith/hope it is true as I would like to battle Gym Leaders and Trial Captains/Kahunas.

I wouldn't put a lot of stock in the video meaning that we'll be visiting another region. This video series had 8 mystery silhouettes that we thought would be our Gym Leaders, but they turned out to be neither Gym Leaders nor Trial Captains. And in the videos, Hoku is treated as the boy's rival, but he picked the starter stronger than his, like a traditional rival and unlike Hau. Since there's already some discrepancies between the videos and games, I wouldn't take the boy moving back as concrete evidence towards multiple regions in-game.

Also, not sure if it's been pointed out, but Exeggcute evolves via Leaf Stone, as it had before. So I think it's safe to say whether a Pokémon evolves into its Alola form is dependent on where the Pokémon was caught or hatched.

But perhaps if we do travel to another region, it is not to battle the Gyms -- but instead explore and challenge the Elite Four and Champion of said region. Although that would be unlikely too..

I wouldn't mind a return to Kanto. *prepares to dodge knives and tomatoes*

Im certainly not going to expect it nor demand it, and all the conspiracy theorists claiming a Kanto trip and gyms all over Alola are entertaining to watch, but are taken with a grain of salt. GF is already going above and beyond with Sun and Moon so far, that a trip back to Kanto would just be more icing on an already iced cake.
