Is there any chance, like a legit chance from official material we've seen so far, he won't be he hero in movie #25 who saves the world? I'm not a Bond expert by any stretch-so correct me if I'm wrong-but Skyfall wasn't about saving the world. It was a revenge plot against M, right? If I'm right, by your definition, he isn't the same character in that movie because he didn't save the world.
Okay, let me rephrase this since this is getting so nuanced: I would like Bond to be the hero of the film whether he's saving the world, M, a puppy, kitten, whales, etc. rather than having him take a backseat to another character just to set up a sequel.
