This is my theory for the next game and any upcoming content

ORAS:
>hoopa wifi and or gamestop event for ORAS
>same with Jirachi

Next Game:
>Pokemon Z (maybe X2/Y2)
>Very possibly on New 3DS in the same vein as Crystal on the Gameboy Color
>Game focus is on zygarde and helps tie all the lore about the war, xerneas and yveltal the weapon and AZ together as well as Zinnia
>more megas and a new form for Zygarde
>Postgame or launch event about Volcanion, possible tie in to ORAS since Volcanion is Fire/Water
>I think it's likely that the girls from the Maison build the battle frontier in Kalos since they move to Kalos as ORAS takes place beforehand
Now my main reasoning for all of this is patterns with past pokemon game releases, and the fact the ORAS postgame has hints at more content.

AZ in X/Y was a play on lettering and a hint at ORAS, I think it's the same deal with Zinnia.

Plus the snake anklet

A= Beginning
Z= End

Thoughts?
