If they want another five movies out of the next Bond actor, I'm not sure that's Pattinson. Craig has been vocal about not liking being stuck with the character for five movies. And Pattinson already has experience being saddled with a less-than-stellar character for movie after movie (Twilight).
I would be more interested in 007 movies rather than James Bond. Keep the universe, put different characters in the 007 position so we get fresh stories. 27 Bond films seems like plenty, I'm not sure how much more can be said about Bond. I would be more interested to see Pattinson as 007 and free from the Bond baggage.
