Update: The original source has already retracted its first info, killing the rumor.

The site who reported this is called The Motley Fool, a long-running financial advice site. Thanks to io9 for the heads up. Here’s the exact wording to start:

Where’d they get this information? Is it true? Who knows. That’s why we’re staying it’s a rumor. But let’s discuss the logistics.

That means by 2016 there could be at least three films building up towards this potential crossover. There’s also the potential Wolverine sequel in there. Make it four. Four films is one short of how many it took Marvel to build to The Avengers. And that’s not even counting X-Men: First Class or The Wolverine, which are part of the universe but hypothetically exist before the introduction of this new Fantastic Four. So by the time this film could potentially happen (for arguments sake, let’s say 2018), they’ll have more ground work set than Warner Bros. does for a Justice League movie.

That is, of course, if this rumor is true and these new movies are being made with this crossover in mind. That’s a big “if.”

If you’d like to read about the plot of the 1987 comic series, written by Chris Claremont, Wikipedia has a good synopsis. It doesn’t necessarily sound like that plot line fits in with what is getting set up in the universe, but it gives an idea of how it might work.

Update: The Motley Fool now has a statement that reads “A previous version of this article inaccurately reported a planned film release that combined both X-Men and Fantastic Four. The Fool regrets the error.”
