A new Mark Hamill interview from Entertainment Weekly led some to believe that the Prophecy of the Chosen One would be reinterpreted in The Last Jedi:
“[Luke] made a huge mistake in thinking that his nephew was the chosen one, so he invested everything he had in Kylo, much like Obi-Wan did with my character,” Hamill says. “And he is betrayed, with tragic consequences. Luke feels responsible for that. That’s the primary obstacle he has to rejoining the world and his place in the Jedi hierarchy, you know? It’s that guilt, that feeling that it’s his fault, that he didn’t detect the darkness in him until it was too late.”
But Lucasfilm’s Pablo Hidalgo says that Hamill wasn’t refering to the Prophecy. Anakin remains canonically the Chosen One.
