...they're likely killing off James Bond, and that woman is taking up the 007 mantle...
It wouldn't shock me to see them off the Craig Incarnation. I watch James Bond movies for the style of schlock and nonsense they bring to the action spy genera, not because I need the main character to have a particular background.
Though, if I recall, the "new 00' Agent", Naomi, played by Lashana Lynch, is likely 007 at the start of the film. Since James puttered off with Swann to retire at the end of the last one (and they don't retire numbers, they assign new agents).
"Paloma", the new Bond girl, sounded like something other than British when she spoke (kind of Hispanic, and apparently the actress is Cuban too), so despite the bond like moves they give her, I doubt she's showing up in the next one unless it's a buddy cop movie with her an Naomi (and even then, not as a 00').
