Don’t get too excited, we may know exactly what this is going to be…
The last two years, and last two Star Wars movies, saw UNICEF promotions via Lucasfilm’s Force for Change. They would hold a “contest” where people would donate money to enter for a chance to win a prize, the most famous one was a set visit to the filming of The Force Awakens.
The current rumor is that this big Star Wars announcement will be exactly that. A new Force for Change contest possibly with Mark Hamill and Daisy Ridley appearing to give the details on it.
So don’t get too excited for a trailer tease or anything like that. We’re only a couple days away from Star Wars Celebration and Lucasfilm is holding the really good stuff for that.
