Pick your choice. One thing that will decide if the secondary region in gen 6 is a new one. Will be the pacing of the anime and when Ash finishes 8 badges. The fool is likely to see all 66 Kalos pokemon by October already.
Clues for Ruby remake/sequel:
Bridgette from PokeBank, could of made new or picked another old character but they picked her. Tell me thats not random. Is Mega Blaziken for the anime only or a teaser? Mega Lati@s is definitely an event. When people buy a game with Latios, its probably the way they get Latias by using XY event. Nintendo released a folder on instagram this month. They say its big news and they can't wait to show us. Besides why does it have a Pokemon 3DS on it?
Clues for a new region:
I bet that souvenir is a battle item like a griseous orb. It can't be transfered in PokeBank so why is it in XY?
