It seems legit, and they all make sense to me atm, it wouldn't be a disappointment to me imo. But I would have preferred other characters
Someone apparently found these codes within the game or something, he also done this before and was "right". Theres a video within the link.
The Batgirl could still be a skin for Batman, its not with the Season Pass watch this video
On a scale of 1 to 10 how disappointed are you? I would be about 3 lol What characters would you have switched?
