I think they've already tarnished it a little at least, if you ask me. He used to just be that quiet franchise where everyone knew his name, yet that's about all the public thought of him until a new movie popped around. These days they try to stick his name on everything, and EA shits out Bond game after horrible Bond game just to make money, while the more recent films have been overhyped considering they've generally just been a bunch of special effects with somewhat mediocre plots. I mean they captured the style of bond, and were exciting enough and all, but kind of lost the mood, for a lack of better way to explain it.
Anyway, since they changed out actors, I just think they shoulda taken a few years break again, like they did after Timothy Dalton. It needed some time to regain its charm.
