The Business Insider has uncovered emails that the script for Sony's Spider-Man spin off "Sinister Six" was due for submission on December 8th; which if everything were on schedule, the script would have been submitted less than a week ago.
Also uncovered in the emails were lists of Sony's release schedule that states a film simply titled "Sinister" is still due out in 2016, and another movie just titled "Spider-Man" due out in 2017 - it is unclear what the 2017 Spider-Man movie is about.
