Slight tangent, but I wonder if any Gen 6 Pokemon will receive Megas this time around. It IS kinda weird that none of them have one, despite Gen 6 introducing Mega Evolution. Then again, I suppose that most of the Kalos mon just aren't that popular, except Greninja ofc.
Ignoring the part where Pokemon fans are, as ever, nostalgia blinded dummies, there's no way Kalos mons don't get at least one mega. Aegislash, Sylveon, Trevenant, Tyrantrum, Aurorous, and maybe Zygarde seem like too popular/likely to just be ignored again.
one does, but tbf its Diancie so its not super accessible
