While there is no proof as of yet, here are 2 speculations regarding his appearence:

The first one is that this Sub-Zero is Bi-Han, Kuai's brother, second SB, ya know. How? After being sucked in the Soulnado as Noob Saibot, it could have killed him, but it could also have him purified and also free him from Quan Chi's spell.

The second one is that this Sub-Zero is a new guy bearing this title, since both brothers died (or did they...) in the previous game and coincidentally, bearing the Sub-Zero titles.

Or it could be Kuai Liang and somehow, he got his human form back.

My english is a bit rusty, so have mercy.
