“It’s time for the Jedi to end…” maybe the title means that a force sensitive person will no longer be called a Jedi, they’ll be called a Skywalker?
The previous film opened the door to the galaxy being filled with a new generation of force sensitive, perhaps Rey and the Resistance choose the title ‘Skywalker’ to denote them as a homage to Luke?
Yeah, this is the theory I was talking about earlier.
