The folks over at IGN say that the villains revealed to be the Sinister Six in post-credits sequence “aren’t necessarily the final roster for Drew Goddard’s upcoming movie.”

The site adds:

“According to The Wrap, the Sinister Six have not been decided on, as the script has yet to be finalized. Apparently, the six teaser images from the credits are “merely possibilities” of what that lineup could be. One insider added that production on The Sinister Six could start as early as January 2015.”
