I guess that's the point, i don't see any reason why Q won't do it on an "Oct 30" delta from the first post, that would be an almost undeniable confirmation to normies.

Of course it could just be another distraction to scare the deepstate and it will be a different date, but then Q wouldn't've needed to say it in the very first post which would undermine the movement if it was a different month/day.
