With that said, I think I'd prefer them going the Daniel Craig route and find someone who we don't know of right now, someone that comes completely out of left field that we really didn't see coming.
That's personal perception though; I've followed Craig's career for years (from Our Friends in the North onwards) and had him tagged as a possible future Bond since The Ice House in 1997 and although he wasn't a 'Movie Star' by US box office standards in 2005 his public profile was just as high (if slightly different) as those of Dalton and Brosnan when they were cast - certainly to UK television audiences and fans of independent cinema.
Well, certainly Craig wasn't entirely unknown before Bond. But I daresay only few looked at him with Bond as a distant possibility. I certainly didn't, not even after LAYER CAKE. And this not because Craig didn't perfectly fit the 'Bond-mould' at first sight, or EON wasn't exactly known for not following the 'safe' route. The biggest obstacle may actually have been objections from the studio bosses who are much less susceptible to inspired casting decisions. And I'd argue both Dalton and Brosnan were a much more traditional choice than Craig.
