Should Bond 26 take place in the present day or go back to the 1960's?
Bear with me on this one :)
In my opinion modern Bond films have several problems they need to overcome for every film:
1) Nowadays there are far more action style film which compete with Bond. It has to somehow distinguish itself.
2) The modern world has moved on and a drinking womaniser is no longer acceptable, Bond has to change if the films are set in the modern day.
3) Technology makes the modern spy less relevant. This was even a theme of Daniel Craig's films which portrayed him as a was a dinosaur and with a lot of the plots being information based. Even mobile phones can cause problems for the plot of a Bond film (e.g. why doesn't he simply call someone for help).
To set Bond apart again, to explain away and justify his character as a drunken womaniser and to remove a lot of modern technology then maybe the next iteration of Bond should be set back in the 1960's. The NTTD ending may have even set this up as a possibility, allowing a reboot of the character back to a very different time. Maybe this approach allows the whole theme of Bond to change and not just the actor playing 007.
