^See, I've always seriously doubted that idea. For one thing. the constant references to Tracy throughout the "old" films. At the very least, Moore is the "same" Bond as Lazenby--and License to Kill
links Dalton's to those two, for that reason. Connery's "revenge rampage" at the beginning of Diamonds Are Forever
implies a connection there, too.
Pierce Brosnan was a "new" Bond--but M refers to him as "a relic of the Cold War," etc.
Perhaps MI6 is very advanced regarding skin grafts (face changes), voice changes, and "de-aging", particularly after Moore?
As for Craig--the idea, remember, is that Casino
on is a re-boot--where the legend is restarted for a modern audience. Effectively, they're acting as if the "old" series didn't happen, and Bond is discovering
the elements we know and love.
