I've heard rumours about another bond movie, but nothing concrete.
I don't think there are any more ian flemming bond titles left.
I know quantum of solace was just taken out of one of his notepads, there wasn't even a story behind it, just those three words
Basically this:
http://www.imdb.com/title/tt1074638/
I think I heard it was delayed because the film company that makes the bond movies went bust
I think I might have been getting it confused with james bond: blood stone (which is a new bond video game)
