GH has prototypes of possible Series 4 figures, too cool!!!
I attached a photo I took at Disney world a few weeks ago. It's of one of the two droid prototypes shown. The droid moves around on a sort of train track, to the left of the que in the first room after you leave the room with C3-P0
I looked through my pics for an image of the other droid but to no avail. I'm sure Kris could help us out when he get's to reading this.
