Dave Filoni announced on Twitter today that we are getting a very spoiler-heavy Star Wars Rebels trailer soon. I have been told that the trailer is hitting tomorrow. It will feature the duel between Ahsoka Tano and her former master Anakin Skywalker, now Darth Vader! Dave said this trailer will feature the last half of Season 2, so we most likely will see aspects of the Mandalore arc, Leia, Ahsoka/Vader, and some of the main crew’s backstories. Keep your eyes open tomorrow for this stunning trailer.
