[Trivial Psychic]

In the case of Sub Zero, since the name is not so much attached to a single person, and is more of a mantle, it wouldn't surprise me if it is neither of the brothers from the original games. His son, or the current leader of the clan perhaps?

I really hope that this line flourishes, and we get Quan Chi (my fave MK character of all time) Jax, and Reptile. I know that the latter two haven't been announced just yet (although Boon's recent clues hint at Jax being next on the roster to come.) I was initially never a fan of Jax, but I really enjoyed the character in MK9, design and playability wise. He was just so much fun, and that figure of him that recently came out....ugh. Mr. Briggs deserves better.

As for Reptile...well, he's the original secret boss until Capcom started milking secret bosses every chance they got. Being that he is also part of a race, wouldn't be to hard to bring him back. Maybe as Khameleon? Either way, I've always had a soft spot for the green guy.
