Theres always possibility I suppose. They could afterall, do a retelling of MK3. If they were to do another spin off game of some sort though, I'd prefer to see it based on other characters.
well it would be a good idea. At the end of Shaolin Monks Quan Chi came our of nowhere with the amulet so maybe they could do one that goes from Quan Chi meeting Shang in the netherrealm to Scorpion banishing back him back to hell. maye scorpion would be a playable character in it. Or each character would have their own version of the story. I reckon it is likely that they'll do another one..
