Warner Bros. Pictures' possible movie lineup for this year's San Diego Comic Con may have leaked online, revealing there are plans for a true "Man of Steel" sequel.

NikkiFinke.com reports their sources claim Warner Bros. will announce six movies during the convention. The Warner Bros. pic line-up includes:

May 2016 - Batman v Superman
July 2016 - Shazam
Xmas 2016 - Sandman
May 2017 - Justice League
July 2017 - Wonder Woman
Xmas 2017 - Flash and Green Lantern team-up
May 2018 - Man Of Steel 2

Warner Bros. has yet to confirm their plans for Comic Con, but it's no the first time the studio's announcements were leaked before the convention. Director Zack Snyder and his producer/wife Deborah spoke to the Huffington Post in March regarding the "Batman vs. Superman" movie leak back in San Diego Comic Con 2013.

"It's kind of a shame that you can't go through the process in a pure way and then be able to announce it in a way that's exciting," Deborah told HuffPost. "With the [Comic-Con] announcement, there was rumblings and we were like, 'Aw.' Because we wanted to bring it to the fans. We wanted to bring them something special. We went to Comic-Con for 'Watchmen' and we were bringing the cast to announce it and it got leaked a couple of days before. We wanted to give that to them and we got cheated out of it."

Unfortunely for Deborah the Comic Con lineup isn't the only information sources allegedly leaked to NikkiFinke.com. The website also reports sources say there will be cameos of other DC characters throughout their movie lineup.

"The cameos will include the already known Cyborg and Flash. Green Lantern [not played by Ryan Reynolds, thank god] may be introduced," the source said. "And Aquaman will be seen in the Justice League movie. Problem is, Warner Bros Pictures was still negotiating with the actors for those cameos and future roles, meaning major contracts for multiple JL/character films to follow. The studio didn't want to move forward until they had more of this secure so they held off starting production for a few months. Seemingly simple reason, but the implications are pretty darn huge."
