Well, to be honest, this reputation of Abrams as the master of deception has been greatly exaggerated.
It seems to me that he just doesn't reveal any information and then fans take over doing most of the work with their theories and paranoia.
As for Cumberbatch, he's young and his star is now on the rise. I see no sense in having Weller take a more prominent role than him.
As I stated in another thread, while JJ Abrams likes his "mystery box" of secrecy, he has never lied to fans about an upcoming movie. I respect him for this attitude. I do not like too many spoilers prior to watching a movie.
