Quite possibly the most revealing Star Wars trailer yet just happens to be the Japanese one. And fortunately for us, it's in English.
This clip, which has surfaced online in the U.S., has a healthy amount of new footage and dialogue. Daisy Ridley's Rey and John Boyega's Finn formally introduce themselves; Adam Driver's Sith menace Kylo Ren tells the scorched helmet of Darth Vader, "I will fulfill our destiny," followed by the previously heard, "I will finish what you started."
Our destiny? Did Vader have a secret son!?
You'll also see lots of TIE Fighter/X-wing footage, more of Kylo Ren's cross-blade lightsaber (it gets dangerously close to Rey's face) and the revelation that Rey has been estranged from/is waiting to find her (Jedi?!) family.
And damn does that desert planet cinematography look great. (Don't get on my case and say it's Tatooine; it's Jakku!)
