I still think that if the whole new 007 thing is genuine, that something plot wise will have James take it back at some point, but then he'll die and the whole James Bond name will become a codename along with the 007 designation.
There was talk back around the time of Casino Royal that Bond was a codename,....especially when Dench continued as M after Brosnan,.....but then Skyfall & Spectre cemented the fact that Bond really was BondI wish they'd done this ages ago, it would put a fun spin on all the previous movies, and would have made more sense in the long run.
The best spot for it in mind was near the start of Casino Royal. Just one line from Dench along the lines of "How does the Bond ID always manage to be given to the degenerate 00's?" While glaring unapproving at "James".
...as what was said earlier, I have no problem having female leads in movies,...create a spin-off as another 00 Agent,....but if they have a female 007 lined up for the main agent for the next film, I honestly think it will fail
