>>28207072YOUR IMPRESSION IS WRONG
EVERYONE'S impression is wrong.
There ARE no impressions.
That's the point. Nobody knows anything. We're all just guessing wildly and grasping at whatever we can get ahold of, whether that's a leak, or a vague supposition about whether it means something for an old pokemon to appear on the japanese website without an alola form appearing, or indeed whether or not the existence of Z-moves precludes the existence of megas or whatever.
NOBODY KNOWS. It's all bullshit and guesswork, and by indulging in that kind of magical thinking, you are only disappointing yourself.
