During a recent appearance at a Q&A session in Des Moines, Iowa (via Gamezone) Stan Lee hinted at some significant Marvel Cinematic Universe developments in The Avengers: Infinity War.
Still, it at the very least suggests that Infinity War will change the existing Marvel landscape in some notable ways.
Although the people with him prevented him from revealing too many details, the Marvel icon hinted that at least one (and possibly multiple) fan-favorite Marvel characters will be introduced during the events of the upcoming Avengers movie.
Unfortunately, reports indicate his publicist stopped him before he continued, meaning the news is as vague as comic book news can get when we consider the sheer size of Marvel’s library of characters.
