And let´s never forget: these are all speculations based on rumours on the internet.
Apart from that, I wonder how Craig´s Bond will be regarded two decades from now. He certainly went from being a laughing stock to the "best Bond ever" - both opinions totally overexaggerated, IMHO. Probably a sign of these times in which people seem only to express things in extremes, not sensible evaluations of pros and cons.
For me, Craig´s looks were jarring at first, I admit it. Of course, he was the total opposite of his predecessor(s). But Craig won me over and I began to enjoy his take on Bond very much. Naturally, he had his strengths and his weaknesses, too. This seems to be ignored by some fans, probably because they grew up with Craig and were introduced to Bond through him. A very familiar dynamic, happening to every actor... well, maybe except Lazenby. (Would be interesting, though, to hear from fans who were introduced to Bond through him.)
Also, I cannot describe him as "the best Bond ever" simply because with Connery and Moore there already were two actors defining the different shades of this character so well. To praise Craig as better than these two feels like disregarding the series´ history. And I´m absolutely sure that the next actor(s) taking over will bring out other ideas for Bond as well, better or worse, too.
The MovieBond is a vessel, and it never stays fixed so no actor will ever be able to incorporate everything the character is about.
