>>40978064I think at the beginning GF did see XY as a direct follow up to BW2 but they needed a reason to explain mega's in the remakes so they created a new timeline to fit it all in with Oras.
Sm later picked up on the retcon with the appearance of Anabel from Oras.
I don't see a problem as the 3ds era is better off not being directly associated with the non mega games.
