Ed Boon, Director of Injustice: God Among Us and Mortal Kombat X, has taken to Twitter to post an image featuring the Greek alphabet. One letter missing is beta possibly hinting that Injustice 2 will be having a beta of some kind.

Please keep in mind this is still a rumor and nothing has been confirmed by anyone involved with the development of Injustice 2.
