I overreated. I thought it was Smoke. It was merely Noob and the costume will be designed/based upon the deception look :/
Look:
Notice his arm? We all did. As well as his V-shaped physique and broad shoulders. But look at his arm, there is some sort of costume related bump. I feel it's Noob, look at what Noob wore previously:
GGs. Before the game's release and before KP1. I made sure there was no way that Boon or the NRS team could miss my tweets, every day I'd send pictures of Smoke machines, cigarettes, Smoke clouds and even Smoke himself. Just asking, no, begging that they make Smoke playable. I hoped he'd be DLC, but no. He is not. He never will be. It's over. I hope to god I'm wrong, when I saw the sillhouette on the left hand side, actual tears came to my eyes and I had to leave my desk. I was so happy. And now that I've looked closer, I've calmed down and came to the conclusion that it's Noob.... OR BARAKA!! That's very possible too. In MKX there was little costume-part thingies around Baraka's arm, and two small ropes over his shouler. The picture also has that, but it still seems more likely to be Noob based on. However look at the fore arm of what I suspect to be Noob but as I type this kinda think it might be Baraka. Compare these images:
and
I don't know. It's early speculation, and tomorrow it should all be revealed. I might take a closer look at the other ones and see if I can find anything.
