Since it's set in Hawaii I wonder how surfing will work this gen. Maybe we'll get a bicycle and a surfboard?
Rowlet and Litten are the better starters, Popplio looks so basic. Hopefully its final evo will come thru!
I wouldn't mind if get some key items that makes us either sit on the back of a Pokémon or whatever. In a similair way the Eon Flute works. It would be more fun if that happens than if we have to sail on ships etc.
