Eh the 3d mk sounds felt too generic to me, the characters didn't even habe their own voices. Of course men sounded like men, women sounded like women, robots sounded like robots and bosses had their own voices but thats it. Hitting sounds were generic as they came and it wasn't eben in stereo. I think that if no one was using specials in a deception match, it would be difficult to tell who was who if you started watching mid fight. My fav mk sounds sets are from 2 and 3, and 9 and x. Also, scorpion's spear sound was the same from 2 through armageddon, not sure about mk bs dc because I neber played it, but I noticed a difference in mk 9 and now you could hear it flying towards you. Also the spear sound for mk 2 is different depending on which port you heard it on.

They are in stereo. I know that the sound system was a bit messed up at the reveal.

So I'm currently on a mobile so don't have the links handy, but there's been quite a bit going on with this game.
Jade and Johnny Cage have been officially anounced; both of which look far more appearling both in terms of gameplay options and personality than ever.  For example I've never been interested in Jade, but I think she might be my first character at this point. 
More importantly for us, remember the enhanced move commands  were going to be different for each character, thereby being a nightmare for us?  Well that's no longer the case, you simply press r1 or right bumper during or after the move hits.  Thank goodness.

also I don't even think the genesis version of mk1 even had a sound for the spear.

I don't like Sonya voice. But Johnny Cage they kept the same voice.
