Which is exactly my point in regards to Kano's heart.
I'm pretty sure that for the ease of mechanics and gameplay, Kano will have an actual heart in his body.
Otherwise, Scorpion and Kotal Kahn's Fatalities would have to be completely reworked, just for Kano, which I don't think NRS is going to do.
I'm pretty sure the animations for the fatalities are the same for every character that it's done on.
Kotal Kahn doing the fatality on Kano doesn't prove anything, IMO.
We likely won't get the answer as to whether or not that's an actual replacement for Kano's heart, until we actually get to play story mode, just the same way that you can't get the story behind Jax's arms by doing an arm X-Ray on him.
For gameplay and Fatality purposes, the bones in Jax's arms are there.
Story mode contradicts that.
