I noticed a few interesting and peculiar things in the video...

Chiefly, I noticed a minimum of six characters (Sub-Zero, Scorpion, Baraka, Mileena, Ermac, (possible) Siobhan) and as many as eight, counting the possibility of Nightwolf and another character resembling Sub-Zero.

So far from Midway we have three TRULY confirmed characters: Baraka, Mileena, and Ermac, although it's safe to assume from the video Scorpion and Sub-Zero are there as well.

Things I noticed...

Going into Scorpion's stage fatality against Baraka, can anyone explain the green glowing square? Could this be a new feature added to excecuting fatalities, like the Fatality stance from MKDA?

Who is the person Sub-Zero is fighting in thisimage? He appears in other scenes but it was only until I saw him pitted against Sub that I realized he could be another character. Is he a new character, or just a mirror or alternate costume of Sub?

Who is the blonde-haired girl with the white hat? Is it indeed Siobhan?

Where do we stand on weapons and multiple stances? Mileena appears several times with her sais but I also remember seeing her without them. I also saw a red ninja character holding what appeared to be an axe. Is this proof of weapon-based combat like in SC, or multiple stances?
