it looks like at the very least the 3rd and 4th character have ironclad release dates, but it's far too difficult for me to parse any of the text. At the very least, it looks like there's a month put down for every character
Yo im super stoked on Sindel, Spawn and even puts up shield Joker. I just hope he isn't copy pasted from Injustice. I know he will probably be similar at this core but I didn't really like him in either Injustice games.
Too bad no Ash though, that was one that had be very excited too.
