Might be kind of weird. I would prefer it all to be rendered.

Real actors would rock. Much better than current cg in my opinion. If it were my decision and i were making a fighting game, i'd get some actors who were also know their fighting, (they don't have to be fantastic actors) get them to act the cinematics and do some (or all) of their character's motion capture, and get a good likeness for their 3d model. I expect mk6 will remain cartoony though.

YEAH!!! Real actors would be fun ! after all, ther characters need a touch of reality...

It depends on the costume design. Some costumes make us real life, non-digital, people look stupid.
