It looks like NetherRealm Studios already has a follow up to "Injustice: Gods Among Us," based on a leaked image of a poster for the game.

It is a week of rumors, game delay announcements, and secret game revelations as this year's Electronics Entertainment Expo, or E3, approaches. In the latest leak, Polygon received word from a Gamestop source that "Injustice 2" is coming out soon.

The source sent a photo of what looks like a promotional poster for "Injustice 2," with Batman and The Flash in the middle of a heated battle. The tagline below reads, "Every battle defines you."

A letter was also sent to Gamestop managers, which says that the local stores will be receiving the posters, which will serve as freebies for people who would pre-order the game. The posters are limited, the Gamestop source told Polygon.

NetherRealm Studios creative director Ed Boon replied to the speculations with this cheeky Tweet.

Forbes reports that the NetherRealm head might have just confirmed the news with this Tweet. Boon also changed his profile picture to an image of the Roman numeral "II". Boon also jokingly asked his Twitter followers if they knew how to de-trend something, as "Injustice 2" started trending on the microblogging site.

Boon isn't the only one who changed his profile picture to this, as many ESL personalities have the same picture on Twitter. ESL League Operations Administrator Brendan Benedict and Wargaming.net World of Tanks Gold League host Joshua Gray both have the big 'II' on their profile pictures, and both has Tweeted "Every Battle Defines You".

The profile picture might be totally unrelated, however, and may have something to do with NetherRealm Studio's other game "Mortal Kombat."

Polygon has reached out to Warner Bros. Interactive for a comment, but the company has yet to respond.

The "Injustice 2" leak is just one of the many leaks the internet has produced this week. ThisGenGaming has reported a possible "Dead Rising" sequel via another poster leak, and some insiders have leaked information about Bethesda's plans to remaster "The Elder Scrolls V: Skyrim" for the Playstation 4 and Xbox One, along with rumored sequels of some Bethesda games like "Wolfenstein," "The Evil Within," and "Prey."
