It's not quite Halloween yet but the 8th annual New York Comic Con in midtown Manhattan was filled with super fans dressed up in their favorite character's costumes Sunday to mark the end of the 4-day event.

Nearly 125,000 fanatics flocked to the Javits center to celebrate everything nerdy and hear comic book and video game execs speak on what they can expect this year, according to New York Daily News. It was the second-largest "nerdfest" in the United States following San Diego Comic Con and the largest pop-culture and sci-fi fest to hit the East Coast.

So it's no surprise that history was made this weekend. USA Today reported that lots of major projects were announced Sunday including the highly anticipated crossover between All-New X-Men and Guardians of the Galaxy set to be released in January 2014.

The title is currently The Trial of Jean Grey and will tell the story of people in the cosmos who find a superhero who once almost destroyed the universe when he was controlled by a dark force has returned to planet Earth and is part of the "original X-Men."

X-Men Group Editor Nick Lowe said, "This is going to be hugely epic in scope, so big that the All-New X-Men lineup will be different after the event than it was at the start of it. To me, as a fan, that level of character change is really the measure of how important a story is."

Other major announcements made this weekend include the return of Stephanie Brown in Batman:Eternal, The Six Million Dollar Man: Season Six comic makes a comeback after the TV version ended after 5 seasons in the 1970s, Aspen Comics plans to roll out two girl power series next year.
