The real Wakanda
Wakanda was in no way the third world country Ross believed it to be, and the trailer revealed the kind of technology it possessed. Of course, we already knew how advanced it was from Captain America: Civil War, in which T’Challa tailed Iron Man without the latter knowing that he was being followed.
It was all thanks to the vibranium, which was only found in Wakanda. Vibranium could be used in all sorts of ways, including for making Frisbees and god-like androids.
However, technological advances didn’t make the Wakandans forget tradition, and this was hinted at in the teaser. From garments to rituals, everything is specific to this country.
The trailer also showed T’Challa and Okoye (Danai Gurira, who was recently confirmed for Avengers: Infinity War) worrying about what Klaw knew and what the world might discover. After all, Wakanda’s riches should remain a secret.
