Craig is actually my favorite Bond. Hope he stays around and does more.
He signed on for 5 more films. With the way his hair is looking, he might need to wear a hairpiece like Connery and Dalton did in future movies. If people were so against a blond Bond, I wonder how they'd feel about a bald Bond.
I think you read some old info. He's not signed on for five more films, he's signed on to do 5 films total, Skyfall being the third.
Five more films after Skyfall would put him at 8 (most ever) and be well over a decade of more bonds with him reaching into his 50's, in other words, no thanks.
The guesses I've seen include films in 2014 and 2016 at that point I assume a new Bond will hit somewhere near 2019.
