>>15304924If there will ever be a Gallade Mega, the earliest time for it will be in the next Mega-batch large enough to be hype-worthy.
...at least this is what my vastly limited knowledge of marketing suggests.
If Pixiv is of any indication, some Japanese drawfags already got hungry for the possibility of a mega [one picture being under spoiler, the other in the OP] in the future.
Though I don't know how Japanese pokemon fandom works regarding Gallade, so I can only raise assumptions.
