If my theory is correct, which is that the survivors of Armageddon will be the ones on the MKA website, then let's guess what they will be doing in Future MK's.
Baraka - I'm guessing that he will be tired of being everyone's bitch, Shao Kahn, Tsung, Onaga, etc... he will become a leader and try and rule all!
Tsung - He will try and kill Kahn again
Ermac - A good guy or guys who try to destroy all evil
Goro - hmmm.. probably will join Tsung
Nitara - She will become my girlfirend
... it's true
Onaga - he will try to take over everythin
Raiden - he won't guide anymore
Sareena - Wants to be with Subbie
Scorpion - Ofcourse, kill that bald headed bastard
Sektor - Goes and tries to recruit stronger warriors into the Tekunin
Sub-Zero - Has to hide from the heroes of the Elder Gods' since he is powerful now
