i really hope it will be gor and bloody,even tough i don't think so.
However the gore scenes are unsensed in the main fighting scenes and now i'll explain why:
if Liu kang kills Shang tsung ripping off his arms and legs,Shang tsung can't comeback for a Mk2 movie,do you understand?
So i think that the minor characters(like masked guards,minions or reptile's animal) will die in a very painfull and gory death.
If we're lucky it ill be a rated R,i really don0t think it will be a 18+ movie,even tough this is the best solution for us.
And BTW this movie will share a lot of things with Shaolin Monks(the real reason why this third installement is become reality,in fact SM is the last game to have a huge success) so exspect Kitana,jax and baraka in this movie(or maybe Baraka not?) and a fighting scene between Reptile and Johnny cage;maybe also kung lao will be in it.
I'm no sure,but if every character uses his special moves at least once,we'll have a gory movie(xample:Cage and Liu' fireball,Kung lao'hat,Kitana's fan,etc).
A mk movie without blood is like a orange juice without orange......

R, obviously.
