i reckon they have been replaced fairly lol they have been in most of the games anyway i think they were due to miss out on the next game (this being deception)
and if u dont know or u dont really read threads some have been replaced
sonya + kano = kira
jax = darrius (i think)
kitana = sindel/jade/mileena
kung lao = well i dunno he is my fav oh joy now i remembered he aint in the game lol lol but yeh thats my opinions

I agree and disagree. LOL.
You see, I really wanted to see the important originals return, fan favorites. I wanted Sonya and Johnny Cage, maybe even Kung Lao.
But if they are not in the game, it really doesn’t bother me anymore. Sonya for example, has been in everysingle Mk game, one way or another, and I like to think that her spot was well taken by characters who needed another chance: Sindel, Mileena, Tanya, Nightwolf, Kabal, etc.
I still think there are secret characters, and some of those you listed have high chances of coming back, so, we just need to wait.

all i know so far bout these super secret fighters i know Montaro is one of them and sonya,cage or lao rnt in this game at all (apart from the konquest mode)

I'm disappointed that Sonya, Nitara, Cage and Kung Lao was left out this time, but at the same time I'm glad that Baraka, Jade and Dairou is in the game. Hopefully all my old favourites will return in MK7. :)
