This poster reveals Kabal is fighting for the side of evil.

It also confirms the Cole Young as the armored fighter we seen in the trailer.

Missing are Raiden, Kano, Liu Kang, Kung Lao, Goro and Nitara, who I am guessing is also CGI and not finished. After the Mileena backlash I suspect they are holding off on her reveal until she is finished.
