Bond 24, which will serve as a true sequel to Skyfall, is only 18 months away from its November 2015 release date. While that's not set to change, production is being delayed until this December, as original Skyfall writers Neal Purvis and Robert Wade are brought into polish the screenplay by John Logan.

A reverese of order was implemented on Skyfall. Neal Purvis and Robert Wade wrote the original draft, with John Logan coming in after the fact to tighten things up. He has been working on the new Bond 24 for months now, with the original team stepping back in to punch up the jokes and add more insight into the past world of James Bond, giving the film a touch of history.

As a pair, Neal Purvis and Robert Wade have been with the franchise for a long time. Their past Bond movies include The World Is Not Enough, Die Another Day, Casino Royale, and Quantum of Solace.

A source close to the project explained,

"Let's call it polite turmoil. People are getting on with their work, but we have to wait for the script, so filming won't begin till December, a few months later than they wanted"

As of now, Bond 24 is keeping its November 2015 release date, though that makes for a rather tight 10 month schedule.
