Will they need to be caught in Alola or simply evolve there?

Caught. Or bred from a mother with the hidden "Alola form" value.

Cubone will likely have an Alolan Form, too. Ground -> Fire/Ghost makes no sense.

Pikachu and exeggcute will most likely remain the same.

Cubone like this anon is saying: >>27697760 will most likely get a sub-species matching preevolution since the differences between the two are too great and that's really what I'm basing this judgement on.

Pikachu and exeggcute both need their respective stones to evolve. So will we see an Alolan Thunderstone or will it just have to been from Alola? A tough call to make, especially with some much time to breed some nice ones before SM come out.

>>27697707
god, imagine if they introduce things like "Alolan Thunderstone" and "Alolan LeafStone"

well... wait a minute. Stone ARE neededd to evolve these pokemon, so what if there ARE new stones to get the Alolan forms regarding those two?

This.
