Why would they spend the time and the money to develop a character, only to not release them? It doesn't make any sense. If they are already working on a character as DLC after this Season Pass, they are going to be released no matter what, because it would be a huge financial loss for NRS, and we all know NRS loves their money.
Also, Atrocious and MMH? I can believe MMH, but not Atrocious. If they are going to add 6 characters, 2 of them are going to be women. When NRS was choosing the cast of Injustice, they chose on many variables, one of them being the gender of the character.
I don't know who your trusted source is, but I would reevaluate what you think of him/her/it.
