Yes, I do believe this. The Sub-Zero that we all see in the Chapter 1 teaser is Kuai Liang without a doubt. We still don't know which brother is in the Story Mode trailer, the one where he tells Cassie that they are not welcome there (I assume "Here" implies that it's the Lin Kuei Temple). Besides there are, I counted, 4 costumes for Sub-Zero. The three new costumes in the variations that we've all (I'm assuming) have seen and the one that looks like MK3 Sub-Zero with a beard in the Story Mode trailer. I'm convinced that we're getting both brothers. However, we probably won't get two different playable characters though. It'll be one playable character with different variations and alternate costumes. Unless there's an actual slot for "Tundra".

@Azuma: Yes, you're right about the ending not being canon but it could still be semi-canonical which would mean that everything accept for Noob winning against Shao Kahn would come true. Why didn't it happen in the Original Timeline is yet to be revealed though.
