i believe there is currently a legal issue going on with static according to this
Since they already did Zod , they can't simply waste the spot, so MM = Next DLC, and Zod will be either:
1-Season Pass 2 along with Red Hood and Static and Zatanna
2-1 Season pass , and Zod will be revealed at the premiere of Man Of Steel as a standalone DLC.
I hope it is 1-
I found some legal copyright notices on wikipedia when reading some names, DC and Marvel and NRS have some same-named chars. such as Static and Scorpion.
