Is there a confirmation that only Cage and Sonya survived Sindel? Because just looking at the scene, there's no way to tell if Kabal and (Cyber) Sub Zero died or not, except that they don't get up anymore afterwards and Sonya and Cage do.
Anyway, I think in the next game since we're fighting the Netherrealm anyway, we'll probably have to defeat those characters for them to come back to life. However, this still holds alot of questions.. For instance, if Jax gets revived, does he get his arms back? Can Kabal ditch the oxigen mask?
Actually, come to think of it - couldn't Scorpion and Noob be revived as well? If Noob is revived and becomes Sub Zero again, that would explain the whole Cyber Sub Zero thing... Except it would leave no Noob Saibot anymore. And this is all if Noob wasn't freed from Quan Chi's control when he got pushed into the soulnado (which means he could ALREADY be regular Sub Zero again, or just stay dead). Maybe it would be better if Cyber Sub Zero became Sub Zero again, but then the whole substory about him being taken by the Lin Kuei would be kinda pointless. Maybe (Cyber) Sub Zero is gone for good, and Noob becomes Sub Zero? So many ways this could go...
Either way, it would be awesome if Scorpion and original Sub Zero/Noob would team up against Quan Chi.
