I certainly hope he does, especially since they are retelling the Bond?Blofeld story. Years ago, They had had Connery as Bond meeting Blofeld face-to-face in You Only Live Twice. Then Connery got replaced as Bond by George Lazenby in the next movie, On Her Majesty's Secret Service, in which Bond marries the love of his life, only to see her murdered by Blofeld. In Diamonds Are Forever, Connery is back playing Bond, seeking to avenge his lost wife. The biggest problem was the lack of emotional continuity due to switching Bonds in midstream. If Craig comes back, then he should stick it out for at least two more movies in order, or just let someone else play Bond (I presume, if they follow the original formula) so that a grieving Bond will be believable.
