I was just thinking, and a little connection came in my head.
Let’s say during this direct, they reveal all of the remaining characters. It’d make sense that they’d like to have all the promotional material with the newly completed banner ready to go right away.
The leak happened only about a week ago, meaning another assumed claim of the leak is that the mural was just printed a week ago, a week before the Smash Direct happened to be.
Hmmmmm....
And before anyone says they might have been printed much early, I doubt they’d just leave confidential and sensitive pieces just lying around like that in some guy’s office for no more than a day.
