Well, I'm not so sure.....
I did some reading on this, and I don't think anything has been set in stone yet. The way I understand it, the beginning of the new movie (to be released next year) has James Bond (still played by Daniel Craig) in retirement. Thus, he has relinquished is "007" designation. There is apparently a scene where M says "come in 007" and this new actress enters. She is not "James Bond", she is the new (at least at that stage of the movie) holder of the 007 designation.
The way I read it, James is drawn back into service to deal with our old friend Blofeld, but it is not clear as to whether is is reinstated as 007 or not. That remains to be seen.
And since they've pretty much run out of original Ian Flemming novels to base (sometimes VERY loosely) the Bond movies on, I think we will see considerable "drift" in future story lines. On the surface of it, I'm not opposed to having a female play the 007 character. There have been a few pretty decent spy movies with female leads, so it's not really new territory. As long as they keep a decent story line and don't go too crazy on the whiz-bang stuff (like they did with some of the Roger Moore films, some of which were pretty awful) I think it could be OK. I'll give it a shot!
