As I recall, the "alternate ending" was also supposed to have Guy Haines, the top advisor to the prime minister that Mathis points out to Bond when Bond shows him the photos.
Frankly, thanks to Bond's quick thinking in the opera, MI6 now knows the identities of many of Quantum's top operatives--including Haines.
I'd say there has to be some
references to this. Perhaps in the "pre-credits" sequence (and PLEASE put a gunbarrel in the beginning, this time!), we'll have Bond rounding them up, in "Diamonds Are Forever" fashion....
