>>29752064-The pokemon league thing was a big misunderstandment. The whole league thing was the promotion for the battle tree, where you can recrute important NPC's of past generations and battle against them. There's no sign of a league in the code as well as int the leaks
-The champion x and E4 x are filenames for Cynthia, Grimsley etc for the tree
From what we know, UB's are catchable. Captain rematches aren't confirmed yet. No post game areas and no Looker/Delta episode kind of post game according to the leaker.
This is very weak. Pretty much XY without the extra town and without the Looker mission, but with some past NPC's in a tower/subway/maison kind of facility.
