That made sense with the old ones, same man just ignore that hes not aging (or his age goes up and down like a super spy Time Lord) while everyone else does.
This isnt the comic Marvel or DC universe though where you can shoehorn various history in together, if this was meant to be the same Bond as Connery or Dalton then you have the problems of the M's being in the wrong order if they are meant to be the same characters.
Why cant this simply be a new version of the same history? Does it have to link up to the old films? Part of what makes films like Casino Royale, Batman Begins and The Amazing Spider-man what they are is that they go back and start fresh without worrying about what came before.
