Wait a minute...seven Arcade skins...
We now have seven Arcade skins

Just like there are as many Crystal Stars, Chaos Emeralds, Human Souls, etc...
Now...forgive me if I'm WAAAAAAAAAAAAAAAAY off base with this, but...could this be a sign for something big to happen? Could they be...THE CHOSEN SEVEN?!?
I personally would love to see an Arcade themed event. Something like what they did with Bilgewater, despite it costing Gangplank an arm.
