Some of these sound a lot like some of my old SW RPG characters (West End Games represent!)
The “ball droid” from the “Force Awakens” teaser trailer = BB-8
Oscar Isaac’s character = Poe Dameron
The mysterious villainous character with the much-debated crossguard lightsaber = Kylo Ren
Daisy Ridley’s character = Rey (no last name yet revealed)
John Boyega’s character = Finn (no last name yet revealed)
