I don't think anyone is really seriously considering Rock is going to make it, except for maybe @Windstar -- even if you're subscribing to his theory that there's only 5 characters left, they would most likely be Astaroth, Cervantes, Hwang*, Lizardman, and Tira, using the story timeline as a predictor. It's not just the events themselves and the timeline, but there is also a theme of groupings in the list all the same, as such:
Mitsurugi (rival)
Taki (rival)
Kilik (the heroes)
Maxi (the heroes)
Xianghua (the heroes)
Grøh (the rival of Kilik/the heroes)
Hwang (*if there's anyone questionable at all, it would be this one - Rock MIGHT go here, but severe doubt - the other option is Grøh's dad, but seems unlikely if he's final boss, I personally vote Hwang because he could be the "rival" of the heroes in that he subbed Xianghua for Korean releases)
Ivy (daughter, also Schwarzstrom)
Cervantes (father, while not Schwarzstrom, original wielder of Soul Edge, could say he's the founder)
Lizardman (Schwarzstrom) (people who argue that Seong Mi-na would go here, it goes against the groupings and makes no sense)
Astaroth (Schwarzstrom)
Nightmare (mortal enemy, also Schwarzstrom)
Siegfried (mortal enemy)
Sophitia (future enemies)
Tira (future enemies)
Yoshimitsu (sword stolen)
Voldo (steals sword)
Talim (seeks balance)
Zasalamel (seeks balance)
Geralt (the guest)

MY FAVORITE PART: voldo sneaking in the background... gently... blindly... stealing a sword from a man with lack of extremities.
CRIPPLE FIGHT!!
