Either way, I want evil/god Liu Kang, and super powered but disciplined Shang from Shang's ending. Also, I'm fully expecting Scorpion to go after Quan Chi in the next one, since he doesn't in this one.
Anyway, the potential is there for the next one, I just hope they can introduce enough new characters, without getting rid of the old ones. That's one of the reasons I love this game, it has all the characters I love, not some of the crappy/bland new ones. Although I expect some guys to show up in the future, since they have cameos in this game (Havik, Fujin, Shinnok, Bo Rai Cho)
