I agree with almost everyone on that list except for Drahmin...NO Drahmin please...very duh character imo, and if anything replace him with Dairou or Hotaru.
I also wouldn't mind seeing Jatakka or Kia.
Fujin and Shinnok are no brainers, they will be in there. Raiden has to come back, I'm sure he will...
Hopefully Ermac will come back but good as he's now freed from Shao Kahn's dark magic, and give him newer moves and if he comes back PLEASE GIVE HIM ARMOR! lol give him the tk toss instead of the push or something, they can do a lot with him.
Scorpion will be back we know.
I'm guessing Sub-Zero will also be back ONE way or another...be it A. resurrection B. a Sub-Zero like character or perhaps Frost(to possibly replace him) or C. a new Sub-Zero all together(which they can very well do being as how Sub-Zero comes from Outworld(his ancestors at least) while he was technically born in Earthrealm(both Sub-Zero's)
Bo and Sareena should be back, but this time not broken to hell please... lol
I bet Kai will be the "Liu Kang" kind of character and Ashrah will be the "Kung Lao" kind of character, I just really hope her spin move Knocks you back and does NOT allow for juggles...and no teleports, really don't need another KL....lol
Nitara and Havik are also musts, need more showtime. Kenshi I wouldn't mind back either.
